Hi,

This is my first post here but I've been browsing these forums for a while and I've found some great information here, so thanks and congratulations on such a great resource.

I've been trying to configure OpenVPN on my DD-WRT router with limited success. After following various guides and troubleshooting some initial connection errors, I can now establish a connection to the VPN server.

However I can not get an internet connection over the VPN. After a lot of trial and error I've reached the point where I really need some help from someone more knowledgeable.

I hope that there is enough info here for someone to give me a push in the right direction. Please let me know if you need any further info.

Thanks for your assistance.

Thanks for the reply.

I have now re-enabled the DD-WRT firewall, but the results are the same.

To answer your question, I had deactivated it when I was troubleshooting some initial connection errors. I - perhaps naively - thought that if I left it deactivated I was making things simpler to prove that the connection worked to begin with and then try and re-enable the firewall at a later time when I knew that it had been successfully tested.

I've just tested that command but it didn't make any difference

I have also set up another client device to test, but the result is the same on both devices. They can connect to the VPN but there is no internet connection.

Yes that worked.

Thanks for taking the time to help me.

Hi,
I hope you could help me based on your previous experience.
I'm on build v3.0-r35034
I'm using internet to connect to an OPENVPN server provided and then I want my internet connection trough that server. I do connect with OPENVPN CLIENT on windows PC and every thing is OK but when I put exactly those settings in OPENVPN Client of DD-WRT I get connected but I can not access internet through that VPN connection!
OPENVPN Configuration:

Connection Establishes:

and here are my "route -n" and "ifconfig tun1":

There are two things that looks a little bit strange about them:
1-Two lines with same destination (0.0.0.0) but somehow justifiable cuz of different Genmasks
2-10.13.0.165 with mask of 255.255.255.255!!!

Why this open vpn connection works on PC and i have access to internet through that vpn but not when run on DD-WRT?

Many Thanks In Advance...

Dear eibgrad,
Thanks for your comprehensive reply.
I'll check and try all the points you mentioned one by one.
Meanwhile what is the build number of the stable build of DD-WRT you mentioned earlier?

Regards

I did all the points gathered and now I'm one step forward:
1-I have both READ and WRITE:
