Browsers use ports in the 2000 and 4000 number range for connections BACK from the server sometimes, so you could use them as they would probably not be blocked.[/QUOTE.

Do you know nothing about TCP/IP and port blocking? You web browser creates a connection from localhost:2000 or somesuch to www.remotehost.com:80 to use the web. Connections with a remote port of 2000 could be blocked while connections coming from port 2000 could still be allowed to run. Firewalls would really disrupt connections to the internet if this was not the case.
