Port Forwarding Question

[Guest Rachiano]

Hi,

I have a general question about port forwarding:

Let's assume I have the following scenario:

I have a router (Hardware router) with 2 interfaces. One interface connected

to the internet and the other interface connected to my LAN. I set up port

forwarding for http traffic(Port 80) to a specific IP address in my LAN. The

server to which the traffic is forwarded hosts a website which runs on IIS.

When a client from the internet enters the url bound to the address of the

external interface of my router the traffic will be passed to the webserver.

Now I have set up the website to log all traffic in IIS. For all connections

an event will be written to the logfile of that specific website.

Now my question is the following:

Will I be able to see the IP address of the host that initiated the

connection in the logfile? (The internet client) or will I only see the

address of the router interface that is connected to my LAN?

For security purposes the original IP address of the client should be

logged. Will I be able to do that with NAT-Port forwarding as decribed above?

 

Please advise.

I'm pretty sure that it will work correctly through the NAT. Should be

extremely easy to test. Just configure it up and see.
