* UDP PCoIP. View desktops and applications send PCoIP
data back to an Unified Access Gateway appliance from
UDP port 4172 .
The destination UDP port will be the source port from
the received UDP packets and so as this is reply data, it
is normally unnecessary to add an explicit firewall rule
for this.
