Problems with VPN Dialer Ver 3.1 & 3.5 and AT&T.

We have users trying to connect a VPN through the Internet from dialer ver. 3.1 and 3.5 to a Cisco 3030 concentrator that are getting the error message "Remote peer no longer responding". The users do not get any type of login prompt and we dont see any errors or attempts to login on the 3030 or the ACS box behind it. The user can ping and trace to the external ip ok so we know they can see it. Has anybody found a quick fix of any kind for this problem?

Also, we have a user that is trying to establish a tunnel after dialing up to the Internet through AT&T's Worldnet ISP that gets the same message. Any ideas about either one of these problems?

Shedds,

Got from one of the fellow Forum Customers.. think this might be it, we are working on getting this into the release-notes..

"Versions 3.1 and 3.1.1 vpn client would connect, but would not transfer any data. Disconnects would occur immediately or within 30 seconds. No errors in client log or concentrator log. MTU was adjusted, IPSEC thru NAT was tried, etc... Upgraded AT&T Worldnet dialer v3.2.1 to v3.2.2 and that resolved the problem."

Hope this helps,

Aamir
