I have been trawling these questions and trying many different solutions to get this working, but I seem to have a problem with getting my routing set up correctly. I have a box installed in a network with no Internet access with the exception of OpenVPN to my server. Everything else is blocked leaving the LAN segment the box is on.
The box opens a connection to my VPN server, so now I have p2p1 and tun0. The setup for /etc/network/interfaces is:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.56.211 netmask 255.255.255.0 gateway 192.168.56.251 dns-nameservers 192.168.100.20 192.168.50.35
The OpenVPN connection comes up and connects as you would expect, allowing me to SSH into the box via the VPN from outside the LAN. The issue is that all outgoing data is trying to use the local gateway. I haven't been able to get any routing configuration so far to pass the following:
- Local LAN via 192.168.56.251
- Secondary LAN (192.168.50.x) via 192.168.56.251
- VPN Server via 192.168.56.251
- Internet via tun0 (OpenVPN interface)
I've tried using
up route add -net 18.104.22.168/32 gw 10.8.4.9
to configure at least one server to get a connection via the VPN, but still no joy. It's like nothing is routing correctly. At the very minimum I at least need to get apt-get working via the VPN and then getting my webserver to go via it as well. I an cope with it being limited like that, but ideally I just want to fix it so the routes are correct!
