[LARTC] redirecting whole subnet

[LARTC] redirecting whole subnet

[Andreas Gietl]

Hi folks,

i'm looking for a method to route a whole static subnet to another static 
subnet elsewhere on the internet.

I think this must work like this:

Packet going to original destination, packet destination is overridden with 
new destination-ip, packet source is overridden with the original destination.

Otherwise the packets will be filtered by the spoofing-protection of the 
routers.

After the packet successfully arrived at the new distination the packet 
should be transmitted to the original destination ip, where it is redirected 
to the original adress.

Could this be done with netfilter? Or is there even a solution more simple?

thanx

andreas

Woudn't tunneling be a better idea?
