Norton Live Update Utility Failing

Strange issue with Norton Live Update Utility. While I reference a Virus Application Utility, I beleive this is a windows networking issue.

I am tweaking a w2003 server with "surface attack" policies, specifically TCP/IP settings.

Local Area Connection\IP Protocol\Properties\Advanced\Options\TCP-IP Filtering\Properties

When I "Enable TCP/IP Filtering (all adapters)" and ADD
TCP: 53, 80, 443
UDP: 53
IP: 6, 8, 17

Save & reboot

Live Updater will fail

When I disable "Enable TCP/IP Filtering (all adapters) "
save and reboot

Live Updater works fine.

I haven't a clue why this is failing.

 

While not a solution, I think I figured out the problem.

Using "Enable TCP/IP Filtering (all adapters)" is a means of filtering inbound traffic to this box. Web services work fine because the destination port is 80/443 on this box.

The problem is accessing outbound services and since the TCP response back to my box is not to a port that I have opened (ie above 1024), TCP will fail to work properly.

I have implemented an IPSec firewall using this link. IPSec Firewall . It's not the only source for the explanation. Simply google.
