Subjectan IP stack problem regarding routing and ARP
Date
Hi, Sorry to bother you all.
My question is about the Linux kernel IP stack regarding routing
tables and ARP.
Basically I am considering a hack on the IP stack for the purpose of
routing emulation(emulating 2 routers in one kernel):

If a Linux box has 2 NICs, I would like to generate some packets in the
kernel, sent them out from one NIC to an Ethernet switch, and then
receive them on the other NIC. Is it possible, with the help of appropriate
routing table, routing rules and ARP configuration? Or the kernel IP
stack must be modified? It seems to me that if the kernel figures
out that a packet's next hop is its local network interface, it will
deliver to that interface through IP stack directly.

Thanks!
