I have a linux box running Redhat 6.0 with kernel 2.2.5-15. I want to set
it up as a router with a configuration as shown below:
eth0 eth1
___\_______/___
| Linux box |
| as a |
| router |
|_____________|
|
eth2 (203.41.227.0)
eth0 and eth1 are my external interfaces while eth3 is directly connected
to my network. So all packets destined for my n/w i.e. 203.41.227.x can
arrive on either eth0 or eth1. As far as my understranding is, within the
kernel code, it is the function "ip_forward" in the file
net/ipv4/ip_forward.c which takes a packet from one interface and forwards
it to another.
My question is : if a packet is destined for my network say from eth0 to
eth2, will it also be handled by ip_forward function in the same way as any
other packet which may be forwarded.
I have not yet subscribed for the linux kernel mailing list. So please cc a
copy of the reply to me.
thanks in advance
regards,
Vinu
