<![CDATA[No WAN and Webgui after adding second Intel Quad NIC]]>Using pfSense 2.5.1. with Intel PRO/1000 VT PCI-E Quad Port Server Adapter. Everything works.

Today installed second NIC (now ET version): Intel Pro/1000 ET PCI-E Quad Port Server Adapter.

pfSense seems to fully boot and new NIC seems to be recognized as igb4 - igb7, but WAN is not coming up and also no webgui. Also all connected laptops disconnect.

Only relevant item in log I can find:

I do not think it is a faulty NIC, as I already tried another with same results.

Would the error "emerg] 6745#100117: bind() to 0.0.0.0:443 failed (48: Address already in use)" be related to the new NIC and no WAN / WebGui?

I also switched the two Quad NICs in the PCI-E ports. After switching the WebGui and WAN were available again and I was also able to enable to new interfaces. Everything now works.

Still do not understand why just adding new NIC in empty PCI-E didn't work immediately. Adding a new NIC shouldn't require any adjustments or analysis (imo).

More likely the ports have been re-ordered because you added more igb NICs. You will have you will have to do some testing to find out which port is now igb0 etc.
