Hi everyone, I'm trying to set up a VPN for remote work using my desktop's Ethernet and WiFi on the same network. My company provides a custom VPN with limited settings compared to self-configured ones. I partially managed it by turning off Ethernet, starting the VPN, and then re-enabling Ethernet, but it caused the VPN to drop when I switched back. I'm looking for a way to route the VPN through the WiFi card without manually adjusting many settings. Anyone have any suggestions or experiences with this setup?

Hi, thanks for the feedback. I did see some improvement by including a route until the updates, but it wasn’t fully effective afterward. I added a route for the VPN IP to connect via WiFi partially before the update, though now both NICs are enabled and I can’t fully negotiate the VPN. Turning off Ethernet works fine for establishing the connection, whether with or without the route, which makes sense since there’s only one NIC—WiFi. When I enable Ethernet occasionally after setting up the VPN, I sometimes lose the connection.
