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
Working from home is great, and sometimes you do need to have access to resources at your office (i.e. the mysql server you’re responsible for, the web server or for whatever other reason). I’ve had some trouble in the past trying to find the best way to set up a vpn client on my laptop (running ubuntu karmic at the moment), and I’ve always forgot how I’ve gotten it to work, so I figure post it here and hopefully this will help you as well.
