Public IP redirects to Router Config. Page

Specs: Windows XP
I'd like to reopen an old thread for a little

I myself have a server set up at my home WiFi
network (with a D-
Link router, port 80 forwarded to my PC on
also port 80) and the
thing is, that when I want access the pages
through my web
browser stuff happens: - works fine private ip - works fine
78.99.x.x/public ip - redirects to my modem

See, I want that other people access those
pages too, through the
public ip, but don't know how.

From the old thread (mentioned on top) I
learned that:
-I cannot access those pages through the
same PC
-but I should be able to access it through
another PC, which I can't
somehow, why?

I would be very thankful if somebody could

PS: I'd also like to know why, when I'm
redirecting ports, "the
starting port has to be smaller than the ending
one", 80 to 8080
works; 8080 to 80 doesn't work

You can't use any 127.x.x.x as anything other than a loopback. You can't port forward to it. Use 192.168.x.x for that or one of the other internal blocks.

Secondly, a source port is a random port over 1024, chosen by the client PC.

A port forwarding rule usually is any to 80 for a web server, any to 21 for an FTP server, any to 22 for ssh..... The list goes on.

Most routers will not allow you to access a server from within the network the server resides via a public IP address. The only routers I know of that you can do this a Belkin routers. The Dlink manual specifically mentions that this is impossible.

If you use your public IP address from outside your local network, assuming everything else is correct it will probably work.

Port 80 is the external port address of the incoming packets. If you set the incoming port on 8080 nothing happens because nothing comes in on port 80. You can direct port 80 to port 8080 which in an internal port. In fact you can redirect port 80 to any port, port 8080 is just a convention as an alternative to port 80.

People on the outside can access your server through your public IP but it sounds like your modem / router does not support local loopback meaning that you on your own pc cannot type in your public ip and access your server.
