Hi folks,

  I'm trying to set up a DEC Multia running an unpatched Linux
2.4.21-pre2 as a wireless ethernet bridge, but bridging doesn't seem
to work and I can't communicate from the bridge to the outside world.

  Here's basically what I'm doing:

  [machine is quiescent with no network interfaces loaded]
  ifconfig eth0 0.0.0.0 up
  ifconfig wlan0 0.0.0.0 up
  brctl addbr br0
  brctl addif br0 eth0
  brctl addif br0 wlan0
  ifconfig br0 [addr] netmask [netmask] broadcast [bcast]
  route add default gw [gateway]
  
  The bridge loads just fine:

  br0: port 2(wlan0) entering listening state
  br0: port 1(eth0) entering listening state
  br0: port 2(wlan0) entering learning state
  br0: port 1(eth0) entering learning state
  br0: port 2(wlan0) entering forwarding state
  br0: topology change detected, propagating
  br0: port 1(eth0) entering forwarding state
  br0: topology change detected, propagating

  Parts of the system seem to work, too. "brctl showmacs br0" (after
some time) shows the ethernet addresses of some nodes on the
network. But I can't ping anything from the bridge, and the bridge
doesn't seem to forward packets.

  The cards themselves seem to work just fine and I've used this setup
for general IP routing.

Here are the loaded modules:

Module                  Size  Used by    Not tainted
bridge                 28800   0 (autoclean)
hostap_cs              67912   0
hostap                 81888   0 [hostap_cs]
hostap_crypt            2032   0 [hostap]
tulip                  57112   1 (autoclean)

  One hub and one switch sit between the Multia and the router.

  Anybody ever seem this? From what I can tell by googling around,
this setup should work. Is the fact that I'm using an Alpha a problem?

  Many thanks,

  Dan
