This is Citrix Metaframe XP 1.3 (2003) server which has been and is still working fine. Yesterday, we connected to a new Internet provider, and thus modified the firewall configuration so that old external IP for Citrix server is replaced by the new external IP. (This is SonicWall; we updated Net Policies and Access Rules.)
I also ran ALDADDR /SET command on Citrix server to change old external IP with new.
From outside the firewall, I can telnet to port 1494 at the new external IP of Citrix server but applications don't show up when Client is launched. Firewall shows some TCP Citrix traffic passing thru but no UDP Citrix traffic.
From my past experierence at other companies, I know that a ICA file specifies TcpBrowserAddress in [WFClient] section, but at this company -- where I am new -- no ICA file was in use. I cannot find such a file on the Citrix server or on the client that was connecting before. (Users connect to the server and then are shown a few folders, each of which contain a group of applications.)
What else needs to be updated/changed on Citrix server (or client?) so users can connect to it at the new IP address? (Internal users obviously have no issues.) Thanks so much.
