[FW1] FW-1 external interface assigned via DHCP

[dgrabowski@FW1-NOSPAMsystemarts.com]

A client has a FW-1 box that has recently moved from DSL to a cable modem.
The cable modem is of the "consumer" grade service right now, and the IP
address is assigned via DHCP.

I attempted to configure the FW-1 box (4.1 SP1 running on NT 4.0 SP6) to
use DHCP, and noticed two things. First, once FW-1 was installed, the box
would not receive an address via DHCP, even with the FW-1 service stopped
(and "control IP forwarding" disabled). Second, when FW-1 was manually
started, it'd cry about not finding the IP address it wanted to see -- that
was to be expected, I guess.

My workaround was to reconfigure the box with a static IP -- the IP that
was originally assigned via DHCP before the installation of FW-1. Worked
great for a few weeks. Then yesterday, it was noticed that network
connectivity was sporadic, and today it's apparent that the cause is that
the IP address has been given to another user.

Aside from the headache of relicensing the box again, has anyone had any
experience with having the FW-1 server using DHCP? The likelihood of the IP
address ever actually changing is on the virge of non-existence, since the
device will always be renewing the same IP.

Any ideas?

(I was wondering if I could somehow install some sort of app on the FW box
that would "simulate" the DHCP request and allocation process -- even
though the box is configured statically.)

Help!
