Firewall and Telent

[lobo66]

for example to test a TCP/UDP port you can:
telnet XXX 123

XXX = hostname or IP address

123 = TCP/UDP port..

If I am running this from location A and B is the destination with a firwall sitting in fornt of it and I am trying to connect to lets say TCP port 1363(NDM), is there any possible way the firewall would be seeing me from port 23 (Telnet)??

The firewall will see the request for the port that you entered after the host and privided that the port is open it should let you through.

For example, telnet to your ISP's mail server by doing ...

telnet mail.isp.net 25

You will be able to connect to it on port 25 and the firewall will only see a port 25 connection and not a port 23 connection.
