| Hi All, I am facing some very interested problem with the Linux bridge. Let me explain you the setup first: wireless STA AP Managed switch ======== ==== ============ | |_______| | ___| | ____DHCP SERVER | | | | | | ======== ====
============ Bridge on AP is br100 = > eth0.100 ath0.100 So here in this setup station is sending DHCP Discover to AP which is received on ath0.100 interface of bridge and it forwards that request to eth0.100. eth0.100 adds its vlan tag and forward this request to a managed switch which can understand vlan tags. then this this switch removed vlan tag and forwards this request to DHCP server. DHCP server then replied to it with DHCP offer packet. DHCP offer is s Broadcast packet. This offer packet is received in eth0.100 but some how it is not forwarded on ath0.100 so that station can also get this. I have verified it by using ethereal that DHCP offer packet is coming to eth0.100 interface but it is not received in ath0.100. One more thing, this is not happening everytime. This is happening
sometime only. So My problem is that like why bridge is not forwarding this DHCP offer packet to ath0.100 sometime. Can any body help me on this. Do let me know if you want any other detail about setup. With Regards Rahul Bhardwaj |
