I think I solved my concern, but not neccessarily the issue. It
appears the strange traffic being block by m0n0wall was originating
from a pptp dial-up client.

Basically, I have m0n0wall setup to redirect inbound pptp traffic to a
LAN connected w2k RRAS server. The remote client workstation was using
an erols (level3) dialup account to gain internet access, then using
the built-in windows pptp component to make a pptp/vpn connection to
our office network file services.

The hair-pulling experience was seeing all the non-LAN ip traffic from
the dialup connection feeding back into our network, via the pptp

If anyone has any recommendations or suggestions, I am more than
willing to hear.
