basic ipf question

[Redmond Militante]

hi 
i have a basic question regarding ipf/ipnat setup.
at the moment my setup is:  

i have a ipf/ipnat box hooked up to a switch, and one internal client hooked up to the switch.  the public ip of the internal client is aliased to the external (xl0) nic of the ipf/ipnat box.

this is working ok for me.  i would now like to add a second internal client.  i'd like to alias the public ip of the second internal client to the external nic (xl0) of the ipf/ipnat box, hook the second internal client to the switch and protect it behind the ipf/ipnat box in the same way that i do the first internal client machine.

this isn't working for me.  when i add the second alias to the external nic of the ipf/ipnat box, change rc.conf on the second internal client, and hook it up to the switch, then reboot both internal clients, they freeze up during reboot.  hitting ctrl-c during the reboot process forces them to complete the reboot process, but only the first - original - internal client is working correctly.  the second - newer - internal client doesn't seem to be receiving connectivity.  am i going about this the wrong way?

thanks again
