This is SIP (STUN gave it away).

Sure, such as they are.
What he says is:
VidyoPortal Specific Ports utilized
Inbound TCP Port 2222 ssh, Server Maintenance (Internal Use Only, DO NOT open
public)Inbound TCP Port 80 Web Access to VidyoPortal
Inbound TCP Port 443 Secure Web Access to VidyoPortal
[Jim] - possible Web publishing rule; may have to be server publishing if the
"portal" isn't using valid HTTP
Inbound TCP Port 10000 Client Connection to VidyoPortal Application Server
[Jim] - server publishing again
Inbound TCP Port 50000 Client Connection to VidyoRouter
[Jim] - server publishing again
UDP 50,000-65,535 Media feeds to/from participants (6 ports per participant)
NOTE: At this time the VidyoPortal Opens all UDP ports dynamically based on STUN
communication between Client and Server so there is no need to open specific UDP
ports on the firewall as long as ports in this range can be dynamically opened.
[Jim] -Like I said; ISA doesn't support SIP, so it can't dynamically manage
these ports
Inbound TCP Port 3306 Middleware DB Port on VidyoPortal
(only needed open if supporting external standalone VidyoRouter(s) across
NAT/FW)
[Jim] - server publishing again
UDP Timeout Change from Default (i.e. 0:02:00 2 minutes) to something larger
(i.e. 3:00:00 - 3 hrs)
[Jim] - ROTFLMFAO!!! Not only no, but HELL no. This is blazingly,
irretrievably, glactically stupid in the extreme. Was this VoIP app designed by
game developers?
Thanks,
Rob

The UDP port script is for use with the UDP update we shipped in support of
MS08-007 (DNS updates).
"openport" is pretty meaningless (as I'm sure you're aware).
Any chance you can share the details?

Hello all-
Running ISA 2006 SP1 on Windows 2003 Standard R2 SP2.
We are testing out a video conference system ("Vidyo"). The testers are having
problems with dropped calls and whatnot, and the Vidyo people have given me a
list of ports to "open." (Including two pages of Cisco PIX commands, though
I've told them we have an ISA server.) There are a few TCP ports that need to
have an access rule. Then there is a large range of UDP ports that need access
(50,000 to 65,535). I haven't done any work with UDP ports on ISA before. Do I
have to use a script to define those ports, like I do with TCP, before I create
the rule? (I looked at isatools.org and saw something called "UDP Update Port
Exclusion Tool." That doesn't really sound right, but is it what I need?)
Also, the Vidyo people said I should change the UDP Timeout to something like
three hours. Is that something I can do on ISA? How?
Thanks,
Rob
