In configuring communication between our MS Proxy/ISA 'Firewall Clients'
and the ISA 2000 Server (through/across our Cisco LocalDirector box (like
a network firewall)), we are trying to determine what TCP and UDP ports
need to be allowed pass-through access. TechNet doesn't provide any
information on this. Various NetMon traces and NetStat captures reveal
either conflicting or wide-ranging results. We're pretty sure about TCP
port 1745 and UDP port 1745. Others?

TIA,
Chris
