Do you suggest trying the following (where pfinet is the path to the
modified pfinet executable):

# settrans -a /servers/socket/2 pfinet -i /dev/eth0 -a <ip> -g <ip> -m
  <mask>

If so, it fails with pfinet: eth0: (ipc/mig) bad request message ID.

Does it work for you?

Unfourtunately, when I try googling for ``qemu'' and ``promiscuous''
together, I get the information about setting up bridged networking
with the guest system and nothing about possible problems with turning
the emulated network card in promiscuous mode :-(

This sounds interesting :-) However, I guess I should wait for antrik
to voice in, since he is the man who should decide what should I
devote my time to. Theoretically, I could just create what I'm
supposed to and then ask somebody who encounters no problems with
eth-multiplexer at his site to test the result. It shouldn't be too
difficult, I'd say.

Thanks for your help!
