OK...FreeBSD is different then :) irqs 24-27 are a little higher than
you can actually set in any BIOS :) Not sure where to go from here,
maybe Scott knows if the em driver is polling or not. BTW, are the
hosts that are on the same subnet the same hardware as the firewall,
and are they also running pfSense, FreeBSD, or something else?
