"TLS handshake failed" on DD-WRT

[mudd1 0]

I'm getting "TLS key negotiation failed to occur within 60 seconds (check your network connectivity)" messages, followed by "TLS handshake failed" when trying to configure AirVPN on my DD-WRT router. I'm using a static IP over a cable modem to connect to the internet. I tried the ciphers "None", "TLS-DHE-RSA-WITH-AES-256-GCM-SHA384" and "TLS-DHE-RSA-WITH-AES-128-CBC-SHA". This last one got me the furthest so far, to the log messages shown below. There's a br0 and a br0:0 device on the router, no br1. I hope I included all relevant configs.

iptables -I FORWARD -i br0 -o tun0 -j ACCEPT
iptables -I FORWARD -i tun0 -o br0 -j ACCEPT
iptables -I INPUT -i tun0 -j REJECT
iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

You forgot the TLS auth key, it is included in the config files when you download them in the config generator.

The TLS-DHE-RSA-WITH-AES-256-GCM-SHA384 is actually the correct one.

Goddammit, I knew it had to be something stupid like that. Anyway, it now works indeed. Thanks a ton!
