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.

Henrik
