What is port forwarding and what is it used for?
HI, I would like to serve a webpage using port 80 publically but privately on my LAN it's available on port 90, now is it possible to handle this ? Currently my page is only available if the user specifies the port 90 after the IP address? I have a net gear router and can't seem to find anywhere to speificy a different private port.
This is easy, but, not a lot of home routers support it.
When setting up a new firewall rule, some give the option of external IP and internal IP.
I do not think that Netgear support this feature... Sorry!
You should be able to redirect the external port 80 to the internal port 90.
As you didn't specify your model, you can look at portforward.com how it works for your router.
If yours isn't listed, it might not support the feature.
Some NAT Routers can do it. Otherwise,
You need port translation software I don't know which.. this may do it
Softperfect Bandwidth Manager it's mentioned here http://markus.revti.com/2009/01/squid-transparent-proxy-server-on-windows-server-2003/ and downloadable here http://www.softperfect.com/products/bandwidth/
if you figure out how to use it, then you can post a better answer than mine! maybe there's other software too, that looks like a 30 day trial.
