[LARTC] Software bridge problem

Dear list.

I have a problem I hope someone can help me with. I am currently developing a "transparent" software bridge that 
connects a local area network to the Internet. eth0 is connected to the "Internet" and eth1 is connected 
to the LAN. The program is working just fine and packets are routed perfectly through the box. However my 
problems goes as follows: eht0 has got an IP stack so that the box can surf around on Internet (this is an 
necessity), while eth1 is protocol less. I want the clients in the LAN to reach the IP stack on eth0 
via eth1 in order to recieve stats on whats been downloaded etc. In this situation packets for eth0 would
be recieved on eth1 and the go through my bridge and  then sent out on eth0 as every other packet. Then when
eth0 has sent the packets it would recieve the newly sent packets in normal manner. However this does not 
seem to work. I have used pktdump to verify that packets are recieved on eth1 and sent out on eth0. 
The problem is that the IP stack will not accept the packets it sends out itself and just drops them. WHY? 
Is there a remedy to my problem??  I am currently running Linux 2.2.22-compact kernel. 

All replies will be deeply appreciated.

Regards,
Henrik Ramberg
