Well, given you've pretty much opened up full in/out access it should be going out.....I would think. From your posting it appears your letting any protocol out on any port and same way on your inbound. Has this been tested without ISA in the picture? Do you know for sure the data is going out and on the port of choice? You might want to sniff to see the traffic. Hopefully some of the other folks will have a lot better insight into it since your going outbound programatically vs. a client browser. sorry John http://www.accuwired.com
