Ports for Client Access

When I connect my PC to the iSeries by Client Access emulator on the LAN, it works fine. When I connect through a firewall, and the firewall only opens the iSeries IP's port 23, then the emulator fails to give the signon screen. But if I us a PC command telnet {400 IP address}, it's OK. Does the Client Access emulator use some other ports for connecting to the iSeries?

Client Access has its own separate ports that you will need to set your firewall to allow. In your case, the minimum will be to allow signon server via port 8476 for a complete list of ports used by Client Access 400. Look here for more information.
