Ubuntu Version:24.04 LTS
Desktop Environment (if applicable):Cosmic
Problem Description:I am trying to connect the “LAN” to the VPN.
Relevant System Information:
I have two ethernet ports. One is WAN and the other is intended to be “LAN”.
Screenshots or Error Messages:I am not setting up my “ip route” commands correctly.
What I’ve Tried:I have tried several times to use “ip route”.
Before Posting:I have checked various websites for information.
I would like to connect a single ethernet port “LAN” at “192.168.2.1” to my wireguard VPN. I would like the LAN to be protected by the VPN. I read that “ip route” would be good for this. “192.168.2.1” pings fine, but can change if there is a better recommendation. “10.164.0.48” for the VPN also pings fine. I would like to do all of this in networkd and I have Pop!_OS (Ubuntu) 24.04. I have two ethernet ports on my PC with one being the WAN and the other intended to be LAN. The WAN part is working fine. The “LAN” may not be configured correctly.

Is there a simple way of doing this with “ip route”? I have tried, but am not getting the command correct. Thanks for any help.
