I bought a new Netgear router today suspecting that my linksys was getting a little old but I still have the same issue with the Netgear router. I can hardwire directly to either router and the VPN connection works fine.
I am using a relatively new Dell Latitude d620 Windows 2000 laptop (sp4), the Cisco VPN software is version 4.8, I use a Comcast Cable modem, my wireless card is a Dell Wireless 1390 WLAN Mini-Card with the latest drivers installed. The new Netgear router is the WPN824 v2 Rangemax.
I don't have any trouble getting on to the internet until after I login to the VPN, once I login (it does let me login using UDP and it authenticates my password) I can't access my work network, my work intranet, my outlook mail or the internet but, strangely enough, I do maintain access to the Pokerstars Network.
I do get automatic windows updates and I installed the evaluation version of MSSQL 2005 a few days before the problem started to occur.
Any ideas would be greatly appreciated.
Thanks!
