Shimo3 is just around the corner and one of its features is support for Nortel VPN. To verify this, we need some people with Nortel VPN accounts, who are willing to test the latest beta.
You can get access to the Shimo3 beta at http://dev.chungwasoft.com/Shimo/ . Just register for a beta account on that site and download the latest beta version. If you encounter any problems or if you have any feature requests, just send me an email or create a ticket on the beta website.
UPDATE: The Shimo3 beta period ended some days ago. So please download version 3.0.
