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