So I have some services and wireguard running locally on a “home” network. I also have wireguard, a DNS resolver, and a reverse proxy set up on a remote server. Since I don’t want to expose the home IP to the public, to access my services I connect to the VPN on the remote, which then forwards my request home. But this means that when I’m at home, connecting to my local services requires going out to the remote. Is there some way to have the traffic go over the switch when at home, but go over wireguard when away, without having to manually switch the VPN on/off?
I could move the DNS resolver (which handles the internal names for the services) from the remote to the home server. But then similarly every DNS request will need to go through both the remote and home servers, doubling the hops. I’d like to use my own DNS server at all times though, both at and away from home. Which tradeoff seems better?
edit: thanks for all the suggestions, I’ll look into some of these solutions and see what works best
I ran into a similar issue when visiting some family. Even though I was connected to home via VPN, my devices wouldn’t pull servers by their IPs. Our networks were setup too similarly. I was able to fix it by editing my conf for the WG connection and added my static servers as allowed IPs. While still having to self host a server for accounting at work, we did a similar split setup so they would be able to use RDP to their desktops but all other traffic was ignored and handled locally. This forum post has pretty good, short explanation with some example config scenarios https://forum.mikrotik.com/t/wireguard-allowed-ips-unofficial-wireguard-documentation/156426
