@NetworkGuy:
Sounds like the pfSense interfaces aren't being assigned properly.
1.) The 2558F has an IPMI interface. On the IPMI "System Information" screen you should see a list of interfaces, BMC, LAN1, LAN2, etc. and the associated MAC addresses.
2.) HINT: The IPMI/BMC interface doesn't negotiate well with some switches and likes being nailed up to 100M Half Duplex if you have connectivity issues with IPMI.
3.) Assuming the 2558 and 2758 are similar, except for the CPU, LAN1 is the lower left port, LAN2 is the lower right, LAN3 upper left, LAN4 upper right. BMC (IPMI) is stacked over some USB ports.
4.) On the pfSense console, go to selection 8) Shell, and type: dmesg| grep igb
5.) Match the MAC addresses LAN1/igb0, LAN2/igb1, etc.
6.) Make sure pfSense, Supermicro and your fingers are assigning WAN and LAN interfaces appropriately
Thanks,
I solved this by updating the BIOS and cleared the CMOS on the A1SRM-2558F, here's more information since I opened a thread in Reddit:
