Re: [FW-1] DHCP Server and FW-1 problem



As has been mentioned, you probably shouldn't be running a DHCP server on
your firewall.  Your firewall should be your firewall, and little or
nothing else.

That said, the only reason FW-1 should interfere with DHCP is if you have
rules preventing the traffic.  I've never done this, but you'll (at least)
need to allow UDP/67 *to* the FW, and UDP/68 *from* the FW, both on the
interfaces that you wish to provide BOOTP/DHCP services to.  Note that your
normal stealth rule will prevent any such traffic, and the rules to allow
the DHCP traffic will need to be in front of the stealth rule.

Of course, you should check your logs for drops on those ports as well.

You may have to define a custom service for those ports.
