There is agroup of network conected to a Cisco 1811 ISR through site to site VPN. Everything goes fine but after 5 or 6 hours of traffic , the users can not reach any more the servers and even when the routers are restarded , the problem remain the same. Only when the server is restarted , the users can log in it. This happen only from users behind the routers. The other users that are in a bridge network , dont have any problem. In routers are configured DLSW for SNA routing.

Hi


do confirm whether the tunnel is between router to router or router to anyother device ?


during the freeze condition did u try pinging the remote peer from the router or from the LAN from where ur trying to access the servers ?


Also did u try checking whether the servers are respsonding welll in their local network ?


do check out whether correct sizing has been done on the server for max no of simultaneous/concurrent user sessions..

The tunnel is between routers.The routers are all 1811 IOS adventerprisek9-mz.12.4-T. The Vpn tunnel is Up and in function.During the freeze condition every workstatiin can ping and via DOS ( telnet ) can reach in any port the servers.Meanwhile in bridge ( local Lan ) everything run fine , No freezing and the servers replies correctly.The server accept a lot of connections because the workstation behind the routers were all in Bridge.
