Watchguard ARP problem |
|
|
Hi,
One of our customers Watchguard firewalls appears to be responding to ARP
broadcasts with it's own MAC address on the trusted network. This is
causing major problems on the LAN. I am not familiar with Watchguard kit at
all, so does anyone know why this is happening (proxy ARP?) and how to turn
it off (if turning it off is the right solution)?
P.S. Please see the ARP table from the Firebox included below. All the ARP
mappings with flags of CMP contain the MAC address of the trusted interface
of the Watchguard.
Thanks,
D.

What model Firebox is it?
What firmware are you running?
When you posted this question on the WG Support Forums, what response
did you get?
I'm running a FireBox II and Firebox III/1000 and an X700 and X1000 at
several locations and have not seen this, but I'm also running the
latest firmware with service patches.

Hi Leythos,
I believe it's a Watchguard Firebox III/500 if that makes sense?
Don't know what firmware version is running at the moment.
I haven't posted on the WG Support Forums?
Thanks,
D.

There is an X/500, don't recall there being an III/500.

For the X/500, it's version 7.3 with 4 hot fixes.

They have a full online forum for registered users that you can access
from their support site - lots of people with lots of help/experience.
