I received a request from one of our developers that I am having trouble solving.

Here in the office they use linux desktops and I can forward the localhost:80 via a iptables nat to localhost:8080. What they want is the same thing at home in windows 7.

I got what I think are two ways of going about this. One to reconfigure the jboss webserver and all the webapps urls (messy). The other is find a way to redirect/nat the localhost port 8080 to port 80. Though in windows 7 I am unsure of how to do this.

Anyone have anyideas on how to do the second?

AFAIK, Win7 has no iptables equivalent. Writing a server that does what you want (listens on a port, copies everything to/from another) should be easy enough. You can find one at this URL: (untested). Using a reverse proxy (Google is yout friend) may fit the bill for http-like traffic. Also check this post:

Doh, I feel like a dummy now, forgetting the term reverse proxy. As soon as I can up vote I will for you. – bdavenport Jan 3 '12 at 14:53

Yes, windows does have a iptables equivalent, it is via the tool netsh and the portproxy interface.

The command to do what you want would be

netsh interface portproxy add v4tov4 listenaddress=YOUR_IP_HERE listenport=8080 connectaddress=YOUR_IP_HERE connectport=80 

Note, that this will only do IPv4 connections, if you also want to forward IPv6 connections you would also need to do

netsh interface portproxy add v6tov6 listenaddress=YOUR_IP_HERE listenport=8080 connectaddress=YOUR_IP_HERE connectport=80

Will this be persistent across reboots? Also the commands are invalid, as I get an error: "one or more essential parameters were not defined" – sorin Jul 21 '15 at 20:03
@sorin it does persist, I use this in a system where I redirect RDP from the standard port to a nonstandard port and I only need to run this command once when I am setting up a new VM. As for the error, you are correct I forgot a parameter for the address (Which I see you fixed, thanks!) – Scott Chamberlain Jul 21 '15 at 20:15
