Ports will suddenly not open using Firewall rules
I'm running pfSense 1.2.2 on a VMM and have added a rule to allow traffic through port 30000 for a Canada Post Shipping module, but after opening it the same as all my other ports (25, 110, 21, etc) it still appears to be blocked. I checked using http://www.yougetsignal.com/tools/open-ports/ and it detects it as closed.
Is there something I'm missing that would prevent a port from opening? I've tried opening other random ports and they don't seem to work either. I do have my VMM tech looking into this, but they aren't very quick.
Appreciate any input or suggestions. Let me know if you need any further details.
just adding a rule does nothing assuming you have NAT.
