We are running a VPN 3005 with software v3.0.2 - users connect using the W2K client (the W2K server is acting as RADIUS) and traffic flows normally for several minutes, but eventually traffic slows down and applications begin timing out. I haven't seen any problems in the VPN log.
Any ideas on how to solve or where to start looking?
My first inclination is to upgrade the software on the 3005 since it is old. If I end up doing so - is there a currently preferred release?
Any ideas are welcome - I want this baby to work well since I may have to be working from home quite a bit this year!
The v3.0.2 is not recommended due to some MTU issues in that built. Thats why its not available at the Cisco website. Kindly upgrade to the latest client versions v3.6.x or v3.7.x and let me know if you still see the issue.
