We recently activated IP Inspect in every router who connect to the main office via VPN. And we're starting to have problem with IP Inspect blocking telnet, ftp and traffic who is not supposed to be block. When we desactivate IP Inspect everything is fine. Or another problem we have, the traffic ( telnet of ftp ) is working for a short time and after the telnet or ftp connection is droped by ip inspect.
Anyone have a solution to my problem. I want to keep every router ( who are directly connected to Internet but also connected to the main office via VPN ).
We use Cisco 871 router with IOS 12.4(4)T4.
If someone could help me with my problem I'll really appreciate
