Yes, I can connect but I couldn't recieve or send any data. I don't know the model of cisco router but this information also gives us some hints about the model. It should be cisco 2511. As far as I know, in order to get terminal screen we should telnet to loopback address that has been defined for this purpose in the router. What I wonder is can we still get terminal screen when I connect to port 2005 of router's IP from Internet (out of the router)?

Can you connect? The command that enables this in the line configuration is: telnet access-server 2005 They need an access-list applied to the router line interface(s) to only allow that from specific (NEEDED) IP's Good job! You found what you are supposed to! -J At 10:34 01/06/2004, Deniz CEVIK wrote:
Hi All, While I am scanning one of our customer's border router, I have seen that TCP port 2005 is open and reachable from Internet. As far as, I know this port is being used for async. connection to other devices in this router.
Is
that normal to see this port as open from Internet? BR --------------------------------------------------------------------------- ---------------------------------------------------------------------------
