We could still use a lot more information about your environment but here are some ideas about how to troubleshoot it. 1) How are you obtaining the 80.33.22.11 address? Are you typing it in directly or using DNS? If DNS, are you sure it is returning the proper address? 2) What packets are being put on the wire by your computer? I would suggest using a package like ethereal (http://www.ethereal.com) to view the packets. What do they have for destination address? 3) What does the packet look like as it enters the firewall? Has anything changed it along the way? 4) Is the packet making its way out of the firewall? What is the destination address? 5) Are reply packets coming back to the firewall? If so, what is their source address? 6) Are the reply packets making it through the firewall? If so, what is their source address? 7) Are replies making it back to your workstation? If so, what is their source address? This way you can at least figure out where the problem is and if indeed it is a netfilter problem. I don't know that much about h.323 but I believe it also embeds IP address information in the packet above the network layer but I'm not sure of the offset. You may want to look at that part of the packet, too.
