Problem only
arp
I have tried setting br0 with an ip address, but found posts
saying not to
use one.
Sorry the MAC for x.x.x.195 is there, i didnt give it enough
time to add it
to the table before i saved it, its on
port 2 and its not local.

Also, I wonder why the MAC address of x.x.x.195 isn't in the bridge
