Yes - what do people use for bridging under FreeBSD with hostap? The
FreeBSD bridging code (options BRIDGE) or the netgraph bridge? With
BRIDGE, I'm seeing the following oddity:

suppose there are two interfaces,

wi0: no IP address assigned, hostap

used with the following sysctls:

net.link.ether.bridge_cfg="wi0 sis0"

Wireless clients can associate to the hostap access point and ping hosts
on sis0 through the bridge without any problems at all. However, they
cannot ping - the box does not even respond to ARP queries
on wi0. Of course, hosts on sis0 can ping OK.

ipfilter and ipfw were turned off for this test, and I even tried it on my
notebook in addition to a net4511 - made no difference.

This is a little bit irritating - I have tried netgraph bridging, and with
that it works as intended - can be pinged both from wireless
clients and from hosts on sis0. However, I'd rather use the FreeBSD kernel
bridge if possible, as that netgraph stuff is a bit cumbersome.

Does anybody know what could cause this problem and if there's a solution?
