Supreme Commander NAT Issues

[Coeus]

Hi all.

I am on a BT Home Hub router (bastard thing) and am having some connection problems. This is try to get Supreme Commander to work with no connection problems. To date I have:

1. Enabled static IP address.
2. Disabled Windows firewall
3. Correctly allowed Sup Comm on my McAffe firewall.
4. Port-forwarded ports 6112, 9103, 30350 and 30351.
5. Enabled my IP address as DMZ (kinda negates the need for port forwarding but did it anyway).

So after all this I ran NATTRACE and get the following results:

NAT test failed. Your router is correctly passing information to and from the internet, but is NAT translating the port numbers on outgoing UDP packets. When your computer sends a packet to a port number (eg 6112) on the server, it should come from that same port number on your own computer - this is not happening. View the report to see precisely which ports are being NATed.

Tests:
Test 1: SUCCESS - Connect to fixed IP
success
Test 2: SUCCESS - Check NATTrace version
success
Test 3: SUCCESS - Perform DNS lookup
success
Test 4: SUCCESS - Connect to named host
success
Test 5: SUCCESS - Direct TCP to fixed IP
success
Test 6: SUCCESS - Direct TCP (web) to named host
success
Test 7: SUCCESS - Direct TCP (6112) to named host
success
Test 8: SUCCESS - Direct UDP (6112) to fixed IP
success
Test 9: SUCCESS - Direct UDP (6112) to named host
success
Test 10: FAILED - NAT check, port 6112
NAT detected (Expected send on port 6112, went on port 60391 instead)
Test 11: SUCCESS - Direct UDP (port 9103)
success
Test 12: FAILED - NAT check, port 9103
NAT detected (Expected send on port 9103, went on port 60392 instead)
Test 13: SUCCESS - Direct UDP (port 30350)
success
Test 14: FAILED - NAT check, port 30350
NAT detected (Expected send on port 30350, went on port 60393 instead)
Test 15: SUCCESS - Direct UDP (port 30351)
success
Test 16: FAILED - NAT check, port 30351
NAT detected (Expected send on port 30351, went on port 60394 instead)

4 tests failed

For the life of me I cannot figure out where its going wrong. Any input would be greatly appreciated. Googling it seems there are quite a few suffering from this but have not found a definitive answer yet.

Best regards,
