I have a site with multiple VPN's configured. Sites with routers (all Cisco) running IOS 12.3 or lower are fine. New routers with IOS 12.4 can establish the VPN link and I can ping the remote networks. When I try to access the Intranet home page from a remote site, the home page appears but I am not able to access any pages. A similar thing is happening with another application (client/server SQL program). The clent (remote site) can logon to the SQL database and perform some task, but then will get a connectivity error. Sites running IOS 12.3 have no such problems.
