Hi,
Trying to set up an OpenVPN server at work, to allow me to connect to the office network from home. (I have full rights on both networks).
My work network runs on a Asus RT-AC66U_B1, which has an OpenVPN server functionality built in.... unfortunately this hides a lot of the complexity from me, which i think might be where I need to dig...
I'm able to connect from my iPad to my work network when I'm at home, but then.... nothing. Traffic is still routed locally, unable to see any resources on the work network. (even though I've enabled all the options to re-route traffic on the ASUS router).
When I attempt to connect from the laptop, the connection times out.
The one 'oddness' in my config is that my Asus router sits behind my ISP's router, so my Asus router's WAN address is actually not directly routable. I'm thinking this is what is screwing things up, but I can't get low enough level access to the OpenVPN install to confirm.
Another thought that occurs to me is both the home and the work LANs are on 192.168.x.x subnet. I suppose this could also cause a problem, but I'd expect a different presentation (If this were the case I would have expected internet traffic to be correctly rerouted, but LAN traffic to fail). I'm reluctant to change subnets just to check, as both my home and work networks have fairly extensive sets of devices that need to maintain the same IP addresses.
Any brilliant ideas?
Thanks

I can’t actually get access to my conf file because its built in to my router, which doesnt expose that to me.... (at least not that I can see)

I suggest you consult your router manual and the openvpn howto ..
And the post above is simply not enough detail to give any conclusion.

My suspicion, is that the problem is being caused by the ASUS router (running OpenVPN) being behind another router and something going wrong with the address translation between the two. Unfortunately the router doesn't give me enough details/logging to actually determine if this is what is going on. Mostly looking to see if anyone else has experienced similar problems...
