Not exactly.
On the iptables-based router there is port forwarding to services running on servers inside LAN. I.e. WWW server is running on 192.168.1.2:80 , in iptables I have port forwarding (nat/prerouting) from external IP (2.3.4.5:80) to 192.168.1.2:80 . Now on 192.168.1.2 in WWW access logs I see internal IP of the router instead of remote IP of the client, which requested 2.3.4.5:80 in browser.
