Recall that there are three contexts, one physical, one in terms of the ESXi vSwitch, and one inside GNS3.Īttaching a new cloud (in GNS3) that uses the GNS3VM interface (in the vSwitch context) attached to the new VLAN (in my case, eth0 -> VLAN30) will bring that new network into the virtual lab.Īt this point I attached a Windows VM to the new VLAN and set it’s interface to DHCP. I could have put the new VLAN deep in the GNS3 topology. In this simplest case, I’m attaching another interface on that same router to a different vSwitch VLAN and routing between them. Recall from Connecting GNS3 that I’ve setup my home network to expect a GNS3 border router at 192.168.25.82 and it will be the route to 192.168.28.0/22. My Internet GNS3 cloud appliance had to be disconnected (you cannot add interfaces to a cloud with existing connections), eth1 added, and reconnected to get it to work. I’m still not sure why, but be alert for this issue if you add an interface.
#GNS3 COULD NOT BIND WITH MAC#
I diagnosed this by using the VMWare interface and the ifconfig command on the GNS3VM to identify and associate names and MAC addresses, but it took a little time to understand what happened. This disconnected the VM because the IP information was associated with eth0. When I did this step, it replaced the existing eth0 on the GNS3VM and made my old interface eth1. I ended up adding two interfaces (more fun!) and also took the chance to set a static IP for my server.ĭhcp4: no addresses: gateway4: 192.168.25.1 nameservers: The interface needs to be added to netplan. To setup the interface, login and choose “Shell” from the main menu. The interface will attach to the VM “live”, but you’ll need to go into the GNS3vm to configure it before it can be used. Next I went to the GNS3vm VMWare properties and added an interface. I created VLAN 30 and called it “GNS3-30” and assigned it to my default virtual switch (vSwitch0). From the ESXi management interface, select the networking tab and “add port group”.
The first step is to go onto the VMWare ESXi server and create a new VLAN on the vSwitch.
The approach I used was to attach the VMs into an ESXi VSwitch VLAN and then use additional cloud appliances to attach those VLAN into the GNS3 topology. The topology will still have a connection “out” to the home network and Internet, but I want to add an ESXi VM “inside” the network as well. Here I want to do something more complex - I’d like to connect ESXi instances into arbitrary points in a GNS3 network.
#GNS3 COULD NOT BIND WITH HOW TO#
I discussed a few days ago how to connect GNS3 into a network (see Connecting GNS3). Most GNS3 users are using a GNS3 VM to host their topologies. Didn’t get that far - yet - but the progress I made is pretty cool in it’s own right. Vagrant got me building VMs in VMWare Workstation, which got me thinking how neat it would be to place those automagically into my GNS3VM environment hosted on ESXi. I have been coming up to speed on Ansible, which got me started on Vagrant. By Brent Stewart on Wednesday, Apr 21, 2021
