Hi: i want to bridge my eth0 interface to several dummy interface, like vmware or xen did, so i can request several dhcp ip address via several mac addresses. but i am stuck in the first step: assume my eth0 is 192.168.10.1, and it can ping 192.168.10.254. ifconfig br0 up brctl setfd br0 0 brctl addif br0 eth0 now i can not ping 192.168.10.254 anymore. but if i set 192.168.10.2 to br0, i can ping 192.168.10.254. and "dhclient eth0" can get ip addess from dhcp server(that surprise me!!) i try to add dummy interface to br0, but dummy interface can not work, like eth0. "brctl showmac br0" give me may mac addresses, so i think bridging is working. i think i must misunderstanding the brindge concept. can i keep eth0 work after it join br0? thanks a lot for your help!!
