I am doing NAT traffic forwarding using iptables (220.127.116.11 => 18.104.22.168) with the following commands:
iptables -t nat -A PREROUTING -d 22.214.171.124 -j DNAT --to-destination 126.96.36.199 iptables -t nat -A POSTROUTING -d 188.8.131.52 -j SNAT --to 184.108.40.206
It works fine except for one thing: If I check apache logs, doing firewall rules etc. on server 220.127.116.11, it looks like all traffic is comming from 18.104.22.168.
Of course it makes a bit sense, since it is 22.214.171.124 that is forwarding the traffic to 126.96.36.199, but I assumed NAT would pass the original IP "requestor" in the package?
Is there a way to make the traffic to 188.8.131.52 have the "real" orignal IP?
Currently, it makes it very difficult to setup good firewall rules and other security stuff as ALL traffic seems to be comming from 184.108.40.206 regardless what the original traffic is actually comming from.
