Actually I think I've nailed it down to OpenSSL. I've installed:

openvpn_2.0-1maemo2_armel
and
liblzo1_1.08-3_armel

I already had an ipcop machine running openvpn, so I generated a config file from it and copied it to the n800. I think my problem is the choice of auth type... when I run the config on the n800 I get an error opening the .p12 file with OpenSSL in parentheses.

What I'm wondering, is the openssl build on the n800 unable to parse a p12 file? In the .ovpn file it includes a line "pkcs filename.p12", from the error I'm guessing this is where it's failing. If anyone has any ideas on how I can fix this, I'd love to hear them, I've been staring at this all night with no real luck.

Thanks
