OpenVPN server IP access
Posted: Mon Sep 27, 2021 5:49 pm
I'm running an OpenVPN server on a Synology NAS that has IP 192.168.1.10. This server also hosts a DNS server on the same IP.
After I've connected with a OpenVPN client to the server, the client is assigned 10.8.0.10 for the VPN tunnel. All IP's in the 192.168 range are still accessible, except for 192.168.1.10, which is a problem for me, because that's the IP that's configured in the client as the DNS server. So basically addresses cannot be resolved.
How can I configure the client or server so that the original server IP is still routed to the VPN/DNS server? If I connect to my router and forward the VPN connection from the router to the VPN server everything works fine, but I'd like to connect directly to the VPN server when I'm directly connected to my LAN.
When I do a route print I see the following entries:
My client.ovpn:
