I''m try to insert a snooping/modifying application in a network without
changing the network. That is, I want to take a linux box with two
ethernet ports and put it between two existing systems without changing
the original IPs. So, I want to change (for example) this:
host(192.168.253.1)
|
|
target(192.168.253.2)
to:
host(192.168.253.1)
|
|
snooper
|
|
target(192.168.253.2)
The snooper needs an interface to listen on (socket) that looks to the
host like 192.168.253.2 and it needs to talk to the real target on
192.168.253.2. It''s not a bridge, packets do not go from the host to
the target, the snooper is
It seems that it should be possible to do this with some combination of
proxyARP, iptables and routing, any suggestions appreciated.
