Sorry if this was asked before ( I'm new in the list ) I was playing with the Fast Network Address Translation (NAT) that came with the kernel, but after serveral tryies I only found a way to translate addresses by source ( but not by destination ). That is, if I told the NAT to: ip rule add from 192.168.1.10 nat 200.9.9.4 and ip route add nat 200.9.9.4 via 200.9.9.1 That behaves OK. The address which are from 192.168.1.10, are translated to 200.9.9.4 using 200.9.9.1 as a gateway. But then, the NAT forgets that the 200.9.9.4 is a translated address. He doesn't answer the ARP's. Any idea ? Does the NAT must remember the translated addresses ? I coudn't find a way to tell the NAT how the translate addresses by destination. Does anyone one how to do that ? Thank you.
