Hello, I'm trying to use bridging in our servers and found a problem with dhcp. Some clients manage to get an IP from the server, using DHCPDISCOVER/DHCPREQUEST. However others use BOOTREQUEST and these don't seem to get an answer. The server sends a BOOTREPLY but the clients continue to send BOOTREQUEST for ever. There are also some (occasional) messages from the dhcp server like "ip length 576 disagrees with bytes received 590" followed by "accepting packet with data after udp payload". I'm using kernel.org's 2.6.17.11. The bridge is created like this: ifconfig eth1 up vconfig set_name_type DEV_PLUS_VID_NO_PAD brctl addbr br0 for i in <range of vlan tags>; do vconfig add eth1 $i vconfig set_flag eth1.$i 1 0 brctl addif br0 eth1.$i done for i in <range of vlan tags>; do ifconfig eth1.$i up done ifconfig br0 <internal-ip> Note that eth1 doesn't get an IP. I also have a question. With the above setup shouldn't the bridge forward packets between all vlans automatically? ebtables says the default policy is accept but pinging between machines in different vlans doesn't work. Does the bridge adjusts the tags (I'd think so)? If it doesn't the switch will block the frames.
