How to route Internet traffic of one VM through another VM?
I have two VMs running as clients of a single host on a single computer. VM1 has a vpn running on it. I want VM2 to connect to the Internet via the vpn. I'm using KVM for virtualization if that matters. All Internet access is wired.
VM1 has two interfaces: its regular Ethernet interface enp10s0 and some kind of virtual? interface automatically created by the openvpn connection, tun0.
I'm thinking the IP address of enp10s0 needs to be the default gateway of VM2 but I don't know what the full routing command should be.
Thank you but I cannot figure out how to use this information, perhaps because I'm not running an actual openvpn server. I have a commercial vpn provider, so the VM running the vpn is actually just a client of my provider's servers.
If you add and configure a private network between the two VMs I believe you can use Network Manger to configure Internet connection sharing on VM1 using the tun0 interface.
tun0 is the tunnel between VM1 and the VPN server which still traverses over enp10s0.
Then why not just connect the second machine directly to the VPN?
Eventually I want the VPN VM to be a gateway for multiple VMs. I'm trying to create some extra security by having applications separated into VMs and networking separated from them all in its own VM.
Also the VPN doesn't run optimally on some linux distros.

Have you thought about looking at how Qubes OS does it? In a VM setup, I think you may be looking for VLAN. If the VM's were to be on separate machines, then you may benefit from VPN. In any case, I hope you do learn VPN and then can explain it to me, lol.
