After moving ports around and changing ports away from Auto settings I
finally ended up putting the two machines on one Cisco switch (seperate
VLANS). So the traffic leaves the switch, goes through a PIX firewall and
then re-enters the switch to the other vlan. Could this be the issue?
Surely a copy should work accross the PIX?
