Sql Namedpipes and Firewalls

[Jaime Alberto Botello Cantú <jbotello @ infosel . com . mx>]

Hi,

We are trying to figure out what TCP ports or UDP use the SQL to 
establish a namedpipe communication.  If we want to allow SQL 
namedpipes connections through a firewall, what do we need to do?

Thanks in advance for any help.
