OpenVPN with Asus Routers

[milleph]

Configured an RT-AC66U client in the UK connected to a private RT-AC68U server in the US using OpenVPN. Stock firmware on both routers. I can see the client in the server's routing table and can connect to both router's web pages using their ip addresses. What has me confused is when connected to the client router wifi in the UK it still thinks it is UK based (ie. google.com resolves to google.co.uk, Hulu doesn't work, etc) The whole point here was to create a US VPN in the UK.

Not very experienced in this but any clues as to what to change?

It's probably the DNS settings which is revealing your original country.
You can check which DNS server is used via ipleak.net

If it's the local one you need to configure dnsmasq to use the VPN's DNS settings: if you would use Merlin's fork you could add such things into the VPN user script "openvpn-event" - which is called on start/stop of OpenVPN.

Not sure if and how you can do this on Asus stock firmware...

It's likely the DNS settings on the WAN tab of the client. If you install Asuswrt-Merlin, there is an option to set the client's DNS to "exclusive" mode. In this mode, the VPN client will only use the VPN server's DNS settings, bypassing the RT-AC66U's DNS entries.

Also, unless you've figured out a way to enable IPv6 in OpenVPN and route all the IPv6 to the VPN, I'd disable it on the client.
