How can I access overlapping addrs through a VPN?

Ok, I’ve added

route 10.1.1.0 255.255.255.0

to the profile and reimported it into the openvpn app, since the iOS version doesn’t let you make those changes in the gui. I’ll find out tomorrow if it works (we’ve left the office for today).

The specific lines are per this post:

Many thanks @cburn11
Wasn’t sure where to start, and that is what I needed to be able to begin troubleshooting.

You would be in a pickle if you had two local networks of 192.168.1.0/24 and every host on network 1 needed to be able to talk to every host on network 2.

If you actually had to have every host on both networks accessible, you would probably be better off switching one of the local networks to 192.168.(not 1, maybe 2?).0/24.

Ok so the thing that worked was adding

route 10.1.0.0/16

to the ovpn profile (I have other subnets).

More specifically,
route 10.1.0.0 255.255.0.0 dev tun
would allow the vpn to connect but did not route to the remote network.

Thanks again for the help everyone!
