hi.
a router is conected to internet modem. a pc is conected wireless to the
router. this pc and my pc are conected network cable. and so i have
internet.
i try to make my pc a ftp and http server.
my pc runs windows vista.
after install software if i go
http://192.168.0.x or ftp://192.168.0.x it
works.
but after i found my ip on internet if i go
http://78.97.129.124 or
ftp://78.97.129.124 it dosnt work.
i disabled pc's and router's firewall. still dosnt works.
does anyone knows why? thank you.
bye.
Firstly, you use port forwarding on the router and forward the ports to the
IP/machine that has IIS running on it, which TCP port 80 if for HTTP and TCP
ports 20 and 21 is for FTP must be forwarded on the router. If the Vista FW
is running, then you would enable the FW exception rules for FTP and HTTP,
otherwise, you won't make contact with IIS. The manufacture of the router
should have a Web site Support Knowledge base to show how to setup port
forwarding on the router.
Secondly, if you are trying to access 78.97.129.124 from a machine running
on the network behind the router, you are not going to make contact either.
It doesn't work that way. You need to go to a machine that is not part of
your network in order to make contact.
Thirdly, you gave up the wrong IP 78.97.129.124 is the Internet IP that the
ISP assigned. It's the public IP that all see from the Internet and how
hackers are going to come at your network and the machine that is running
IIS. The 192.168.0.x (whatever) is a private side LAN IP behind the router,
and it cannot be seen by the outside world.
Fourthly, and not trying to be smart with you, you have no ideal as to what
you're doing. Hackers look for machines like your machine, because they can
hack it and use it as a jumping off point to attack other Web servers and
networks and you won't even know it's been hacked, which can happen in a
matter of seconds once you open those ports to the public Internet. This
will be due to you not knowing how to harden the O/S, IIS, user accounts,
registry, and file system to attack for a machine that is exposing a Web
server to the public Internet.
And lastly, there are entire books concerning the security aspects and the
howto(s) for this, and seasoned professionals can hardly do it, let alone
some home user out of the gate trying put up a hack bait Web server.
