Here is a small report of "gotchas" discovered while playing with 2.4.9,
etherdivert and/or the current experimental br_netfilter 20010830-1
patchset.


--- etherdivert ---

iptable nat rules only work on the interface having the same MAC address
as the bridge interface.

workaround:

a) If you only need to divert packets on one interface then make sure
this is the interface with the lowest MAC address. If not, rearrange
your cables to match this requirement.

b) If you need to divert packets on more than one interface then
reassigning the MAC of your interfaces to all have the same MAC may
work.


--- bridge_nf 20010830-1 br_passthrough ---

same problem as for etherdivert. Only alternative 'a' seems to work
somewhat reliably. Reassigning MAC addressess seems to work sometimes
but not always.

The REDIRECT target bombs out if you haven't assigned an IP address on
the ethernet interface. Better to use DNAT and specify the IP of your
bridge interface.
