Please tell me if what I'm trying to do is feasible.
I have a router named "R" which is connected to WAN. R allows adding rules to the routing table. There are numerous of machines connected to the LAN port of R, they all have ip addresses 192.168.1.* assigned with DHCP on R. Among those machines, there's a machine C with ip address 192.168.1.100. I want all traffic of other machines in the subnet to pass-through machine C where some filtering and logging will be done.
Is this possible? Is there a name for what I'm trying to do? (so i can do more googling later)
EDIT: C is running linux
