Did you ever get it going and uploaded it here? Sounds interesting.
I have just created a DD-WRT build with openvpn feature (chk format) for WGR614L.
I have tested it with static key configurations .
I will upload it to the community site once I m done with the testing ... In the mean time if some one is interested in trying /testing this , he/she can send me a PM with his/her mail id ....
I have created this thread to get feedbacks about this build .....
I just bought two WGR614L routers. Now I can test it with VPN support. Can you send me this firmware?
