IOS router 12.1 dialing into Internet using ISDN and can establish the IPSEC tunnel with the PIX at the remote end. PIX configured with dynamic IPSEC config for this connection. Tunnel is established when a ping is initiated from a PC behind the router to a server behind the PIX. But applications like telnet, www are not working (timed out). When a telnet is started we can see that the router is encrypting the packet but no similar decrypting counts increasing in the PIX. With Ping the counters are incrementing normally both sides. Is this anything do with the IOS version? Any help will be appreciated. Can provide more information if needed. Thanks, Murali.
