Hi all,

Has anyone managed to get encryption/authentication working with OpenVPN? In server mode using tls-server I just get a floating point exception when starting up OpenVPN. If I put the WRT into tls-client mode it starts up but then I get the same floating point exception when the remote client connects and tries to authenticate. I also cant get PSK working - I get the following error:

Sat Jan  1 03:13:34 2000 Authenticate/Decrypt packet error: cipher final failed
Sat Jan  1 03:13:34 2000 Fatal decryption error (process_incoming_link), restarting
Sat Jan  1 03:13:34 2000 SIGUSR1[soft,decryption-error] received, process restarting

I would really like to hear if anyone has managed to get this going!

Thanks, Dan

I did get PSK working without any problems. Haven't tried public/private key stuff yet.

I did use OpenVPN 2.0 (-11 I think) both on the server and the client (WRT).

I managed to get PSK working, it was my fault! I didn't put the same cipher setting on each side. Once I'd done that it was fine. Still can't get certs working though, but I'm happy enough with PSK for the moment.

I have OpenVPN working on my WRT54G in tls-server mode, but only if I use Linksys's gcc (I also get a floating point exception when I compile the OpenSSL library with openwrt's toolchain).

That sounds like gcc bugs ? How can I use the linksys gcc BTW ?

Hi,

to use the original linksys compiler or to generate a working libssl for the WRT54G V1.1 follow the instructions of that page here:

Thanx, great!
