General Questions

Hi all,
I am using the latest Monowall in my network as a router.
It is setup to allow all connections through from both the Wan side and the Lan side so it just acts as a router.
This works ok for everything on our network except when we use a Canopy Radio that has Nat turned on.
When we have a customer behind the radio with Nat turned on, we notice that in the Arp Table that the Mac Address for the Radio running Nat changes.
It will change the first letter of the Mac address and it changes every few seconds. I am not sure why it does this, I think it is the software inside the radio and how it handles Nat.
If we turn Nat off on the radio then we see in the Arp Table the Mac address is correct and works properly. Only thing is that we need to use Nat in our situation.

Can anyone think of any way around this issue as when the Mac Address changes the radio is no longer able to surf.
If I go into the Arp Table and delete the entry for the radio then it will immediately be able to surf again.
I would like to be able to enter in the correct Mac Address and IP address into Monowall somewhere so it always uses this address and see if it works.

Any help would be appreciated.
