Collaber

Hi all!

 After setting up collaber in a LAN behind a proxy and firewall I would like to see an option to change the ports, which will be used by collaber to communicate with the relayserver. Because in most  cases the networkadmin will not open additional ports. 

Why not using ports 80 and 8080? 

A second issue is, what is going on when the (maybe only one) public relay server is not available?

Regards
