[Bridge] bridge wont forward when ip address changes

hello :)

I have been using the bridge utils for a long time now and its been very
good but there are a couple of issues that I came across when trying to
setup a wireless bridge...

Firstly I currently have a setup like the following ...

Computer A --- Wired Network --- linux box ---- wireless link ------
linux box ----- Wired Network --- Computer B

I have bridged the wireless interfaces and the wired interfaces together
on both of the linux box's and data can travel across the wireless
bridge without any trouble but if I attempt to change the IP addresses /
subnet of Computers A and B the bridges seem to stop forwarding packets
and no data get through at all, its like they aren't learning the new
addresses.

If I restart the 2 Linux boxes then everything starts flowing properly
again.

The 'Linux boxes' are a couple of Motorola Wireless Access points
running OpenWRT.

Does anybody know why this might be happening and what I might be able
to do about it?

The other issue is that the this bridge setup doesn't seem to forward
any NetBIOS traffic, however, i'm not too worried about this its more of
just bring curious.

Thanks for your help,

Matty.
