I followed your steps but still can't get traffic across the bridge. If I use the server's interface through the cloud I get an IP address but I still have a slow connection which is the issue I'm trying to solve with the bridge.
Hi, I followed the instructions, however, I install a remote GNS3 server on ubuntu 22.04 The installation has been completed successfully. About GNS3: I choose the option: run application on remote server. I upload cisco IOS 7200 through Dynamic preference. I uploaded it and it was successful. However, I need upload image of ne40huawei and I have problem with QUEMU. Output error is as follows:The selected server does not support KVM. A Linux server or the GNS3 VM running in VMware is required. I hope you help me

However, I not sure how to install a GNS3-VM on a remote server and interconnect it with it. Note: The server is a Dell R630, It has a environment that I must not affect. I was allowed to use a physical server space to set up a lab. I hope you help me
after reboot xe interfaces are disappear what should i do
Thank you for this... the one piece I did not try was simply removing the Cloud device and adding it back. I have been struggling with it not showing up but now it works great.
Wow man, it's exactly that I was looking. Thanks a lot!
Thanks so much, I have been trying to get my vcp and vfp to talk to each other with no success, but you hit it on the head at the end. Your right, very little videos out there and content to learn from, not even real books like cisco have. Getting images for gns3 has been difficult.
Thanks for the kind words. Yeah I would agree, I actually made this video to help me figure it out the next time I have to do it.
Dude great video. One question... Im trying to use 1:1 NAT for my IPsec connection, do you know if I can do this same configuration (using VIPs, 1:1) or if I can do it using something like a outbound NAT?. Im struggling to set this up using just a Phase 2 tunnel, and try to NAT/route everything thro. Thank b4hand
Are you trying to NAT the traffic going across your tunnel? My assumption is you would use a VIP or NAT pool. Fortinet also uses the term VIP so finding information may be tricky, let us know what you find!
Hi James, can we do the SIP Trunk routing via pfsense?
SIP trunking, do you mean port forwarding for your SIP provider? In most installations I have been involved in as long as phones have layer 3 connectivity back to the BPX everything works. Take a look at these two links, one is from the pfsense community threads, and the other is a video on port forwarding. If you have more details I would be happy to try and help! forum.netgate.com/topic/96755/overview-on-configuring-pfsense-firewall-nat-for-voip-sip-phones/3 kzread.info/dash/bejne/Y414uMebes-tkrA.html
thanks so much for taking the time to make this video, its highly specific but It helped me out of a jam and i would not have figured this out :) - fellow network engineer
Hi..thanks good video...I have few questions, here RE is the control plane and PFE is the data plane. Why host connected to RE not to PFE? I may wrong. Anyway I would appreciate if you can show how to setup evpn vxlan using qfx. Thank you.
Too bad the channel isn't alive anymore :( The content was great
Dude thank you so much for this video lol
hi, I would like to add a remote vm (hosted on proxmox as the gns3 linux -gns3 server-) as a node topology. Is this possible?
You can can setup KVM images as VMs and run them inside of GNS3. What I usually do is connect to the VM using a virtual bridge, so you wont see the vm but you can connect to the network its on. Here is a video I made about that. Ask on one of the GNS forums and let us know if you learn anything else! kzread.info/dash/bejne/aaFrmbN6nNrfYdI.html
thnx man! nice toturial
Thanks, it helped alot
Have you been able to get your proxmox vms to interact with your GNS3 server? It would be great to use those vms instead of new instances of the same thing. Edit: Great video! Super easy to follow.
Thanks for the great feedback! As to your question, you will need to setup a virtual bridge, I already have a video on that! kzread.info/dash/bejne/aaFrmbN6nNrfYdI.html Hope this helps!
Great video, mate. Perfect and in detail. Would love to see more Juniper videos from you. Maybe a JNCIA or JNCIS/JNCIP course 🙂
I have thought about it, my primary goal is to create content that is missing, i feel like there are already some good courses out there (just got my jncis-sp using the course official Juniper course (which is now free). I also have some great Juniper books on my website (older but good). mylilserver.net/networkArticles/jncissp.html
@@regularnetworks3570 Okay, mate. Thanks. 🙂
Amazing work Man. Thank u!
Very good video. However, how to modify the GNS3 configuration file? Because it's in python and there doesn't seem to be a conf file. Thanks very much !
Im not entirely sure why you would need to modify a configuration file one the server, I have always interacted with it via the desktop interface. Maybe a question for their fourms?
LOL @ R300 There is asong that is well known that was out years ago, Let it go, let it go...... LET IT GO! Small setup sitting in a Data Centre rack???? But sensing its just a plant room
You call subnets strokes ?
In the ISP space its short hand to denote the size of a subnet in cider notation. The size of the subnet is usually more important than the actual addresses in the subnet, dynamic routing protocols handle the actuall addresses (you do have to staticky set them on the interfaces though.) It is commonly written as '/30' (point to point link). The enterprise world usually just uses /24, so there is less of a need to define different subnets lenghts. Now thats for IPv4, IPv6 is all /64s. There are some RFCs that say use a /127 on point to point links, and others that say dont (it happens in practice and is just fine). Subnetting IPv6 beyond a /64 is strongly discouraged. Hope this helps!
this was very helpful.Thank you
Thanks for the great video! I tried going down the path of converting the ESXi VM. I got it to working, but would not recommend. How do you update the server? Do you just do apt update/upgrade, re-run the GNS3 script, or do you trash the VM and have to start from scratch again? My hope is apt update/upgrade or re-run the GNS3 script options.
Ohh exciting! Yeah I used the ESXi image for a while, exciting to hear a comparison! I can make a video about updating this week, but this is the short version: Because we added the repos its apt update. you can do an 'apt update ' to refresh your package database then 'apt search gns3' to see the current version that's available. The update does not go live until you reboot all associated services, i just reboot the entire VM. Takes less than 3 minutes.
@@regularnetworks3570 Thanks for the reply! That's the answer I was hoping for and reboot would not be a problem in my setup.
Awesome I like it! I went ahead and made a video about how i do it here. kzread.info/dash/bejne/fnyYw6pqiNLalKw.html
Good video
Reguular~ very unusual video- talk you later. ;))
Thank you very much for your video. I couldn't get the NAT working. "Error while creating node from template: NAT interface virbr0 is missing, please install libvirt". Kindly advice
Check out this video, it may help you. The short and long is your are missing libvirt and you will need to install it. kzread.info/dash/bejne/aaFrmbN6nNrfYdI.html
What do you run Proxmox on? Please share your homelab setup ;>
Consider it done :) Also thanks for the excitement, I appreciate it! kzread.info/dash/bejne/Z4Jor5Opp5CrlrA.html
Excellent videos, both this and the Proxmox one! I got GNS3 running on Proxmox, and installed and modeled vMX exactly as you demonstrated, but I can't console into either plane and it's doesn't look like the telnet ports are actually up when running a port scan on GNS3 VM. I'm on Proxmox 7.2, all the latest packages.
Unfortunately I dont have any insight on Proxmox 7.2, I know there were some issues with 7.1 so I have just kept mine on 7.0 (still running debian updates though). Be sure that your processor type is set to host and see what google has to say, good luck!
Great content over here, the video adds to your previous one on how to install gns3 on a remote server. For this video, I was unable to get the Juniper vMX 18.2R.1.9 image and could not ring juniper support, kindly help and share with me the file or an alternative link to it
Hi Ashaba, thanks for the complements. Unfortunately I am not affiliated with Juniper and can not redistribuite any of their software. You will need to contact Juniper support.
Good video! Hope you keep making and uploading Juniper basic labs for the beginner.
Where we at with the web ui promised a couple years ago?
I am not affiliated with GNS3 or its development, however there is a web ui, but I do not use it. You can ask over at the GNS3 forums, they are super nice.
I am testing versions 20 and 18 but I can not booting up them on GNS3
You may need to downgrade your Proxmox version. There was a bug in version 7.1 (I am still running 7.0). Try installing it as a standalone VM on proxmox.
Could you please tell why you choose exactly 18 version for uploading to GNS3? Do you have any insides that exactly this version good for virtualization?
It was the version Juniper supplied, which all works out. Most major features (at least for routing) have been in place since version 17.x. I have been studying for the JNCIS-SP using this setup, I will let you know if it was not adequate.
Hi eugeneonline, just a quick update I took the JNCIS-SP exam last week and passed, this lab was more than enough to prepare me. You should be fine using version 18 for now. As far as I know there have not been any major changes.
@@regularnetworks3570 thank you. I didnt mean to use newer version. I just ask maybe you know that this exact version is better for virtualization. Congratulations with your achivement!
@@eugeneonline2010 Thanks!
Thank you for sharing this video!
Very helpfull thanks
Hey man I just started doing Juniper stuff and I noticed that you haven't posted in a while. I don't know if you got discouraged or something but I would love to see more content from you. Could you by any chance also show how to initially configure a vqfx switch? Thank you.
I appreciate the words of encouragement! I actually have a newborn at home now so recording is a lot harder, that being said I was planing on doing the vQFX, even started it over the weekend. Should be out soon. I am thinking of doing some BIRD IPv6 stuff for BGP and OSPF in a mixed environment after that.
Congratulations on the baby and I can’t wait to see the new content. As a guy that’s transitioning from Cisco your videos really help a lot.
Hi ThiccBrown it took a while but I have finally made a install video on the vQFX! Its a pretty temperamental device but it works! Come to find out I was having a lot of trouble with a bad image. kzread.info/dash/bejne/dHqGu9OSfM_Hp9I.html
Even I have persmisions to download vMX Eval, there wasn't listed 18.2 any file available to download, maybe 17.1 did show as option to download. But looking at your screen I rang juniper support. So thanks for the tip.
When you rename interfaces for FP rename Adapter 2 as NotUsed and start from Adapter 3 as ge-0/0/0 then interfaces will match with GNS3 when you enable to show interfaces. Well, that was actually in earlier versions. Now maybe not.
Yeah honestly the naming is a bit confusing. I have been working on getting the vQFX running it has been the same headache.
Lovely video... easy to follow along.... my install was successful
I see fpc 0 as present state for some reason not coming online connected as mentioned pls advise thanks
This means the vCP and vFP are not communicating. Its most likely the em1 is not connected correctly
for some reason mine doesnt show g/0/0/0 interfaces in the cli with the show interface terse command i get these other obscure names for the interfaces
That means your vCP and vFP are not communicating. Near the end of this video I have some troubleshooting tips (19:08 - Troubleshooting) give that a review, and if those dont help let us know! Its most likely your em1 connection is not on the correct interface. Sometimes it can take a while for both components to fully boot and negotiate with each other, espeically if your vm has little power.
if it's only ge-0/0/0 not shown? So seems it just not displayed in sequence, but if you have any ge-x/x/x and you sure that you have done everything right then maybe find where in this guide docs.gns3.com/docs/how-to-guides/importing-vmx-and-vqfx-into-gns3/#legacy-vmx-the-single-vm-pre-release-versions says about in CLi root@% grep vm_ /boot/loader.conf. But this possibly was more in older versions.
@@boolve Yeah that is for the legacy vMX (14.x i think) that came on one VM. I was wrong about ge-0/0/0, it is out of sequence as you suggested but does work.
Thank You so much, Appreciate your Great Work.
Thanks I appreciate hearing it! I have been told that you don't understand something until you can teach it, so part of my goal is to further my understanding :)
i have problem with running qemu images, i get no console output (black screen). Device are up and running but console gives nothing. Do you have any idea what could be the issue?
Same problem here, hope somebody will figure out the problem
Can you check the VCPU type on the ProxMox server and the console type? The proxmox server should be set to host, and you want console set to vnc. I can make a video going over these if you need it.
The problem is in the newest kernel.. I got the problem when using Proxmox 7.1 but when I downgrade to version 7. 0 everything works normal..
@@munandaraddin871 Can I put this solution in the video description?
@@regularnetworks3570 of course
Great! Waiting for eve-ng installation on proxmox.
I could do an eve-ng video, I also have it running on ProxMox currently. Truthfully I find myself using GNS3 more and focus most of my time there. If I remember correctly its all installed from one ISO, if you want to do it you would be able to follow the first half of this video with the correct ISO. I have the server provisioned the same way as in this video.. I might put it on the list though :)
