RE: gretap tunnel redirecting 2 different networks on destination host to nics

Update on this. 
Pinging from 172.16.1.y to br0 is not received, cannot see it arrive 
with tcpdump on eth2. However doing a broadcast ping is being seen on 
eth2.

I managed to make this windows server unreachable somehow. So I extended 
the test just by simply adding eth1 to the bridge.

This did not seem to affect the connectivity of 172.16.1.x. However from 
this point, I could not ping from the br0 172.16.1.y anymore. Although I 
see with tcpdump icmp and arp packets on the eth2 interface and nothing 
on eth1.

When I only remove eth1 with brctl delif br0 eth1, ping is working to 
172.16.1.y. Do you know what this could be?
