Hello, I want to have to IP interfaces in different subnets using a bridge and eth0 IP1 | bridge--+ IP2 | | +-----eth0 but only IP1 at bridge really works, at IP2 arp does not work, I can reach only hosts, for which I enter arp entries manually with arp program. If pinging IP2 from outside without manually entering their MACs into arp cache, their MACs appear in arp-cache of bridge , but not in that of eth0. I binging outside hosts with IP2, arp cache of eth0 allways has 00:00:00:00:00:00 and flags 0 for their IP, is that a known bug or did I miss some configuration ?
