I finally figured out how to get Ubuntu to connect to a Nortel Contivity VPN. It took quite a while to find the right app and configuration, but after a lot of search, I’ve found a package called vpnc (vpn client for cisco3000 VPN Concentrator). The project homepage is found here and it is supposed to work with:
* Cisco VPN concentrator 3000 Series
* Cisco IOS routers
* Cisco PIX / ASA Zecurity Appliances
* Juniper/Netscreen
