 Subject:  collisions issue
 Date:  Mon, 18 Sep 2006 11:29:23 -0400
I think I seem to be having problems with collisions.
The collisions are incrementing at about 1 per second.
I need some advice on how to troubleshoot this.

Not sure if this is coincidence but, m0n0wall is showing the WAN port
as simply being 100baseTX, not 100baseTX <full-duplex>

The physcial connections for this router are:

--inet--IPS--m0n0wall--LAN

the inet connection is a 100mb feed from co-lo provider
the IPS is a device from 3com/TippingPoint
