windows 2003 port forwarding...

[renzki]

i have a problem with my port forwarding stuff... this is my setup

i have a windows 2003 server with Routing and Remote Access (NAT) enabled... this computer is connected to the internet with a static ip dsl connection... i have also enabled iis in this server...

i have 3 other computers (WinXP) in my LAN connected to the win2k3 server with their own configured static ip addresses... to the three computers i have installed a web server for each... ive checked the setting for these webservers and theyre working perfecrtly fine...

now i configured the win2003 server to forward http requests at ports 81, 82, 83 to each of the computers in my LAN. but when i try to browse my websites in their respective ports i am not redirected properly... is there something wrong with my setup?

sample config:

http://[server ip]:80 ---> win 2003 server iis (works fine)

http://[server ip]:81 ---> webserver 1 in LAN (does not display the page)

same for the other two servers...

what has gone wrong?

Hi there

Maybe if you explained what you'r goal is with this setup i.e. what you are trying to achieve and why, might help us determine the problem.

Is the following correct:

- dsl/internet connection > Server 2003 PC (via modem)

- Server 2003 PC > network switch [with Cat5e]

- The 3 XP computers are connected to the network switch

I ask just to help us know for sure what physical setup you have.

I've never done port forwarding with 2003 so I'm not gonna be much help but have you made sure that port forwarding works in the firewall settings and exceptions. Not sure of the settings offhand but I dunno, it may be a thing to try

Regards and hope this helps others help you lol

yep.. that setup is correct... and my goal is to hopst 3 different websites behind my LAN that is visible to the internet.

@renzki - as far as I can see, your setup is completely correct. You have no hardware firewall in place to worry about opening the ports in question. The only thing I can think of at this point are DSL provider or switch limitations-- I was curious about this myself so I went searching in a broadband forum.

It could apparently be an ISP limitation or some firmware setting you neglected to address in the switch (the latter of which is unlikely it sounds like but I say it FWIW.)

Are these xp computers running iis on port 80 (default)? I'm assuming you have used rras to forward ports from the external ip address and specified port (ie external ip:81) to the static ip of the particular computer and port (ie static internal ip:80) Is there a firewall setup on the internal computer? If so have you opened the port?

Can you surf to the xp computers website from the windows 2003 computer? If so you are setup correctly on the xp side and there is an issue with the config of the server.

When you say http://[server ip]:81 I assume that you are using the external ip of the server and not the internal ip? I just had to ask for clarification...

If you can surf to the external ip and you get your 2k3 webserver I doubt the ISP is blocking any ports.

So you want to host different websites....

WHy not run them all from one server on port 80?

You can do this by altering the host headers.
