I just tested eth-multiplexer that doesn't set the ethernet card in the 
promiscuous mode, and it can still work.
In order to exclude the possibility that setting the ethernet card in 
the promiscuous mode can cause the problem, you can remove the 
corresponding code in eth-multiplexer.
The code of setting the promiscuous mode is in 
eth-multiplexer/ethernet.c. Remove the function call of set_promisc() in 
ethernet_open() and ethernet_close().
Maybe it can help.
