I need a client on my network to communicate with a remote system through my ISA 2000 Server.  I need to send UDP 9500.  I have created an IP packet filter to allow 9500 udp send.  I also attempted to create a protocol rule for UDP 9500 and it still does not work...

Please help...

Did you try to use UDP Send Receive?  Check the logs to see if there are any bounced incoming packets from the remote system also.

Packet Filters and Outbound Access Control


" ...Outbound Access Control for ISA Server clients should be done with Protocol Rules and Site and Content Rules. However, only the Protocol Rules have influence on protocol access, since Site and Content rules are focused only on site names.

When you create a Protocol Rule, ISA Server will allow inbound and outbound access to ports specified in the rule. You should never need to create packet filters to support your Protocol Rules. If the Protocol Rule is not working, then you should check for other factors that may be causing this situation."
