This is my setup: A -- [tap0 B iwi0] ~~ wireless ~~ AP -- C -( internet ) A is a qemu VM running on host B (but I see similar behavior when a wired interface connects a laptop to B instead of VM and tap0). I'd like to make B act as a bridge so I did this: ifconfig bridge0 create ifconfig bridge0 addm tap0 addm iwi0 up <edit rc.conf so that it has ifconfig_iwi0="WPA"> /etc/rc.d/netif restart iwi0 ifconfig bridge0 <iwi0's old ip address> I do see traffic from other machines such as C coming in on iwi0 and going out on tap0 (as it should). But C does not see any pkts from B. So I did this: ifconfig bridge0 ether <iwi0's mac address> Now B is once again happily exchanging pkts with C. When A sends out dhcp requests they go out iwi0 but nothing comes back and C does not see the original dhcp requests. Am I correct in thinking this has to do with the WPA mode? May be the interface mac address is used in some way or is the AP (Linksys WRT54GS) doing something? I am using WPA-PSK and running -current of two days ago. Also, when I ping B from C, this works fine but I see some funny things on the tap0 interface. An icmp echo request turns into the following! 01:22:36.688601 IP truncated-ip - 7096 bytes missing! 190.2.179.15 > 122.160.138.29: ip-proto-205 01:22:37.689380 IP9 bad-hlen 8 01:22:38.690216 IP8 truncated-ip - 27274 bytes missing! 107.80.159.197 > 18.31.117.141: ip-proto-236 01:22:39.691139 IP6 , wrong link-layer encapsulationtruncated-ip - 41480 bytes missing! 85.216.108.207 > 88.35.66.234: ttp ... Is there any way to make this work (bridged packets going out on a WPA protected wireless link)? I can use NAT and a local dhcpd on B and avoid bridging but NAT and NFS don't get along (that is, I can't mount C's filesystem on A). Thanks! -- bakul
