However this behavior is not what I want/expect from netfilter. I'm looking for a simple, straight-forward, connectionless 1to1 IP NAT. And, of course, i'm looking for something that can be enabled/disabled without waiting minutes! Ok then, if that's the normal behavior of netfilter's NAT module, I'll have to find an alternative solution. Thank you very much for your help.
