I'm trying to make a Nortel VPN and my FC5 laptop talk to each other. NetworkManager + vpnc doesn't seem to have much luck -- I just get a cryptic error message. Novell has another implementation called turnpike which according to their docs might work, but I can't get it to build on Fedora. Nortel's own client, such as it is, doesn't look like it'll ever work - not that I really want to touch a closed-source IPsec implemention anyway. Anyone have better luck?

These notes might be the key to making it work, but it doesn't seem like it's been integrated...
