Check duplex mismatch, physical connections need to be consistant, if 100 full duplex in the firewall the other end needs to be the same, check cabling as well if duplex is not the issue.

you may want to also clear the counters after you correct physical.

it's not speed and duplex.( they are negotiated correctly as per the o/put ).

it's a bad cable on that interface.

replace it.
