ports/protocol through firewall

[Bill Tangren]

I run an nntp server (inn-2.4.1 compiled from source), on a RHEL ES4 
machine, behind a firewall (that I don't control). I have configured the 
server to accept secure (SSL) connections on port 563. Access to this 
server on this port behind the firewall works fine. I asked the firewall 
admin to open port 563 for nntps traffic. He opened port 563 for tcp 
traffic only. From outside the firewall, I cannot get access to the news 
server.

Does anyone know if it is necessary to allow udp traffic as well for inn 
to work over SSL?

Thanks!
