Windows Port Forwarding

Neon · Posted: Thu Mar 11, 2004 11:21 pm Post subject: Windows Port Forwarding

I don't know how many of you run Windows as an internet gateway (I know I have to for technical reasons) and one thing that I wanted was to forward ports. I searched a bit and finally came up with this great program:

NetworkActiv AUTAPF 1.0

Its freeware and TOOO easy to use, allows advanced IP filtering so you can change what IP addresses to allow or deny. Great little program...

Thought I should share the wealth Smile

Finally I can now send stuff through mIRC Wink

Ohhh very nice ! Now someone find me a good SSH server for windows (yes I know there are cygwin ports).. I'm currently using a program called Foxit WACserver which is pretty nice but only allows two simultaneous connections...

I don't to sound slow, but what is Port forwarding. I never caught the concept. Anyhelp would be appreciated.

Port forwarding is basically that you connect to a port on the gateway machine and it automatically forwards you to aother port on another system.. its useful for security and for natting.

SSH portforwarding is more complex, featuring both local and remote port forwarding via encrypted tunnels, you can read the openssh website description since they have pretty pictures explaining it.

Port forwarding is as simple as following:

Code:

[ INTERNET ] [ PRIVATE NETWORK ]
CLIENT ----- > 193.1.2.3 : 80 ----- > 10.26.122.27 : 80

So a connection from a client in 64.92.162.82, port 80 will transparently be forwarded to the 10.26.122.27, port 80, that is a host of a private lan that does not have an interface to the internet (which makes sense in many topologies). Obviously 193.1.2.3 should also have an interface on the Private Network to be able to contact and forward.

Of course there is no reason of why it can not be

Code:

[ INTERNET ]
CLIENT ----- > 193.1.2.3 : 80 ----- > 193.1.2.4 : 666

or

Code:

[ PRIVATE LAN ]
CLIENT ----- > 10.26.122.27 : 666 ----- > 10.26.122.27 : 80

or anything else.. Wink

[EDIT: Whops Sahirh I didn't see your post.. Had open the browser tab for a while Smile

As a rule of the thumb, you can find the homepage of most applications by quering google.com for their exact name, among the first results. The homepage for AUTAPF is here

i tried to run NetworkActiv AUTAPF 1.0 from ma XP desktop but it gives me the message that unknown publisher, then it says the file is not a valid win 32 application.

So what the way out of that?
