There's your problem. Your "IPS" device is set to not use
auto-negotiation, but always force 100 Mbps/full duplex. Since your
m0n0wall's NIC is set to do auto-negotiation, it drops to 100
Mbps/half duplex, and that's why you're getting collisions. So either
force your m0n0wall to use 100 Mbps/full duplex on WAN as well (by
modifying config.xml manually - see
http://doc.m0n0.ch/handbook/faq-hiddenopts.html), or simply set the
IPS to do auto-negotiation.

This is a classic problem and not at all m0n0wall-specific.
