I have a box setup as a router using Iptables (masquerade), logging all network traffic.

The problem:

Connections from LAN IPs to WAN show fine, i.e. SRC=192.168.32.10 -> DST=60.242.67.190

but for traffic coming from WAN to LAN it will show the WAN IP as the source, but the routers IP as the destination, then the router -> LAN IP.

I.e. SRC=60.242.67.190 -> DST=192.168.32.199 SRC=192.168.32.199(router) -> DST=192.168.32.10

How do I configure it so that it logs the conversations correctly?

SRC=192.168.32.10 -> DST=60.242.67.190 SRC=60.242.67.190 > DST=192.168.32.10

Any help appreciated, cheers

Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect. But I cannot log in from the WAN. I'm missing something. The VPN server is using a pre-shared key (L2TP) and… >>> More

I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud...

This is a weird one, so I'll try to explain in as much detail as I can so I'm giving the whole picture. As I've mentioned in my other questions, I'm in the process of setting up a new Cisco 881 as my WAN router and NAT firewall.
