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