I have a Cisco 1841 with Frame-Relay 128K. The site is connected to head office via VPN connection. All connections work fine via VPN but only one http connection! I can ping the address, but telnet on port 80 does not go through.
I diabled CEF on the router and changed the ip tcp adjust-mss to 1300. telnet worked for once, then stopped working.
Everytime that I change the MSS or ip mtu, the connection works once then it stops working.
Any idea what the problem can be and how to fix it?
Thanks for your help,
