Does it proxy all of the traffic if I have a firewall with two
ethernet cards in the same subnet?

i.e. if I have

router --> x.x.x.5 <- bsd -> x.x.x.6 --> x.x.x.*

and I turn IP forwarding on, will it allow the interior network to
'see' the router?

How should I configure the two interfaces?  Should I use a netmask of
0xffffffff for x.5 and 0xffffff00 for x.6?  Will routed figure
anything out?

I did a news search for ARP_PROXYALL and found basically nothing -
where is this documented?

Thanks.
