RE: [FW1] local.arp changes still not picked up



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Make sure the format is:
a.b.c.d	xx-xx-xx-xx-xx-xx

It is important to use a tab character, and a dash in the MAC address
a la NT. The proxy.arp file on my main firewall contains on over 200
entries on five different interfaces, and I've done it on 5 firewalls
now without a problem.

Make sure you have the MAC address that matches the interface / IP
address. This can be very confusing on WinNT. e.g. the 'route print'
command prints the interfaces in reverse order to the network control
panel, and uses the loopback as IF 1.

Sadly, the new proxy ARP entries still didn't take after a
fwstop/start,
and even a reboot. The old one still works fine. The network objects
and
rules are patterned identically to the working one, which was set up
according to the instructions in the Phoneboy FAQ. I clearly must be
missing something, unless it has to do with the limitations of
Windows NT
4.0 Workstation, or the fact that the internal NIC is Token Ring. Any
suggestions or leads would be greatly appreciated.
