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? +-----------+ | BR0 | 172.16.1.y | | 172.16.1.x --------|ETH2 TUN1|------- | | | | 172.16.1.x | TUN2|------- --------|ETH1 | +-----------+ -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
