Do you have any ipf/ipnat rules on wm1 and wm2? You probably shouldn't (but 
that depends on what you actually want).

Also, see /usr/share/examples/ipf/mediaone for an (old) example of how to 
configure an interface with a dynamic IP address. The recommendation in that 
example file is to use "ipf -y" in dhclient which forces a manual resync with 
various kernel interface lists. 

It's been a very long time since I last had a dynamic IP address, but that 
media one example is where I would start planning my firewall.
