Redirect internal IP to external

blacblu · 17 May 2012 at 00:03

So, my problem is that I can't access a page hosted on my computer.

I have a page (http://localhost:50892/Default.cshtml) and want my friend to access it through the Internet, what kind of configurations should I do on my router?

aro87 · 17 May 2012 at 00:19

Forward TCP port 50892 to your local IP address.

blacblu · 17 May 2012 at 00:56

I did what you told be and asked to my friend try "myexternalIP:50892" on his browser, but it didn't worked at all.

Screenshots from my router configuration.

You shouldn’t need to be messing with port triggering at all.

Does the Virtual Servers Setup automatically open the port, or do you need to manually open it?

Is the machine at 192.168.1.2 running a firewall, and if so have you allowed traffic on the required port?

Is your friend remembering to include the http:// before the WAN address?

CanYouSeeMe.org is useful for checking that ports are open.

He probably wasn't using "http://"

But why is this necessary?

I tried using CanYouSeeMe.org but even with the port opened it didn't worked, according to the site the problem is that there is no route to host.

Is your firewall on that machine setup to allow access to that port?
Can you access it from another machine on your LAN using 192.168.1.2:50892 ?

There is not any kind o firewall or other blocker installed/running on the PC in 192.168.1.2

I also can't access the page through other machine.

Then something is blocking it dispite you saying there is no firewall on. What are you using for the software to host pages?

By anychance do you have a dynamic IP given to you by your ISP?

It's not even working the local side of the router yet.

If it's a Windows machine, do a netstat -a from a command prompt and see if the machine is listening on port:

C:\Users\temp>netstat -a

You should one that says
TCP 0.0.0.0:50892 YOURMACHINENAME:0 LISTENING

If not, the software is not working.
If you have one, then there is a firewall or something else blocking.... either that or the software if configured to be bound to 127.0.0.1 and not 192.168.1.2

Microsoft Web Matrix

There you go, the software seems to be working properly.

PistolPete · 17 May 2012 at 19:56

And it also shows that the machines IP is 192.168.1.4, not 192.168.1.2 as you configured.......

Sin_Chase · 17 May 2012 at 20:00

It's listening on loopback only and not your LAN ip. You need to tell web matrix to listen on 192.168.1.2.

But, your netstat says you are listening on 192.168.1.4. This would indicate that your LAN IP is not 1.2 at all.....

blacblu · 17 May 2012 at 20:12

Seems that my internal IP for my PC changed one on of my router resets, either way when I try to run "http://192.168.1.4:50892" from other machine nothing happens.

Also, web matrix is not a proper web service app, it's a development tool. Use IIS.

No he's not - 0.0.0.0:50892 is the designation for listening on all IP addresses of the machine and perfectly acceptable for inbound connections from a remote host, it is not the loop-back address.

If they're not specifying the protocol (http://) in the address bar then the connection may fail dependent on browser.

Personally, I'd set the external PAT to do TCP 80 to 50892 myself...

Quite right, I read the 127 address below and not the 0.0.0.0 bind.

Eitherway, web matrix is a development tool and not exactly suitable for hosting as the level of control given is limited at best.

blacblu · 18 May 2012 at 00:46

But accessing "http://192.168.1.4:50892" from other machine on the network shouldn't open the page being hosted by WebMatrix?

Probably not.

WebMatrix uses the very limited IIS Express to host the site during development.

If you want to use the site in anger you’ll need to publish it to a full version of IIS. If you want it running locally have a look at ‘Microsoft Web Platform Installer 3.0’, or install it via Control Panel->Programs->Programs and Features’.
