[Durham] Hi guys Openvpn and various routing

I assume you have OpenVPN setup to redirect the default gateway?

Problem is, the connections to your minecraft server could come from anywhere, but as the default route is redirected to the VPN, the replies will go out the wrong route.

So, you probably have a couple of options… if it’s just Netflix you are needing to send over the VPN, then find the correct IPs and setup static routes for these to go over the VPN, and leave the default gateway pointing to your router.

Option 2 would be to setup some policy based routing…

This can be complicated depending on your setup. If your odroid is acting as a router for the network for Netflix, etc.

Can you provide more information on how it’s setup, and what you want to achieve? i.e. some kind of digram of the network setup?

> Ive got an Odroid-U2 at home running minecraft server for my daughter.  Ive decided to connect it to my openvpn server in the USA so I can get all the new american shows on Netflix.  However Im not sure how to do routing for the minecraft server.  As it stands all traffic from the odroid is routed to openvpn in the usa.  Is it possible to write a rule to push traffic to the minecraft server outside of the vpn tunnel as currently her friends connect via her domain name thats pointed at a dyndns address on her homehub.  Or would I be better off adding a rule to my openvpn server and point her minecraft domain name at the vpn in the usa and then get it to push that traffic down to my odroid in the tunnel?  If so would I need to add any special rules to iptables or openvpn in the usa to allow this to happen?
