Hello,

I have some problems with the fullowing:

I have one box (123.123.123.123) from with I would like to forward all 
traffic comeing to this box to another (12.12.12.12). This should be 
transparent for the clients. So if I do a http or ftp request to 
123.123.123.123 the answer (webpage, ftp login) comes from 12.12.12.12.

I like to have this but not for ssh (so I can login to 123.123.123.123).

I thought that I should do

iptables -t nat -I PREROUTING -d 123.123.123.123 -s 0/0 -j DNAT --to 
12.12.12.12

on 123.123.123.123

But it dosn't work. Do I need to setup something on 12.12.12.12?

Thanks,

Alexander Newald
