OpenVPN coming from DD-WRT



  • Ok, bear with me as I'm not the most savvy on ovpn. I just bought an Alix 2d13 setup with 4GB CF card running pfsense 2.0.1 embedded. It's running fantastic and smoother than I thought once I gave up on using the wireless on it and using a separate AP (I digress..)

    I used to use ovpn on DD-WRT where I had the key put in I statically generated, used UDP transport, compression LZO, TAP. I would end up getting an IP on the DHCP range on my normal LAN subnet. I would like to recreate that same thing on PFsense but I keep getting TLS authentication error. I'm not sure I set it up right. I installed the TAP fix so I can do this, but it seems like I'm missing something else. Also, pf asks for encryption algorithm and I don't think I ever had to mess with that on ovpn/dd-wrt, or DH parameter length, or server certificate. In fact, I thought I was doing a no certificate method. It says weconfigurator default *in use for that now. Server mode is Remote Access SSL/TLS.

    This is what I get on the client:

    Wed Sep 12 11:15:38 2012 UDPv4 link remote: x.x.x.x:444

    where it just hangs forever until I disconnect. The logs on pf say this:
