: Hi Rolland,
:
: Thank you for your prompt reply. Sorry for having been vague when I
: used the term 'my computer'. When I used it saying 'my computer's ip
: address' in my first post, I meant for the IP that each of the
: computers connected to the router will get when going to a website
: that tells the user of the Ip adress, such as
: http://oi.sfsu.edu/cgi-bin/student/whatsmyip. When I used the term my
: computer saying that it is ' is connected, along with another two
: computers' into a router' I meant for the computer where the dfault
: wevsite and the IIS 5.0 is (192.168.0.2).
:
: I read what you said about OUTSIDE connection, and I would appreciate
: it if you could tell me what I have to do in order to uset eh PUBLIC
: IP
: to get from outside into the website. Do I need to tweak the router?
: If so, please tell me exactly what I need to do, since my previous
: attempts to change the settings did not really help me.
:
: Thank you in advance

When you link to the web site that tells you what it sees as your external
(public) IP address, it is seeing what is assigned to your router. If your
router is running NAT, then every internal user surfing the net uses the
same external IP address. The router keeps track of what requests are made
so returns can be routed appropriately.

However, if your ISP promotes your web server, in a DNS zone for your public
IP address, then it will be pointing to the router's IP address. The same
as what is seen as in the previous paragraph.

Ex. If your public IP address is: 200.200.200.200, then your router will
have to allow port 80 (default port for web servers using HTTP protocol)
inbound and route it to 192.168.0.2 (Internal IP address of your web
server). The internal users will point to 192.168.0.2 to get to the web
server because they are behind the router/firewall.

How you specifically set this on your router, depends on the make and model.
If it is a SOHO router, most have a web interface and can be reached with a
web browser using the internal IP address of the router or LAN Address of
the router.

If the router is: 192.168.0.1 then http://192.168.0.1 will get you there.
You may be asked to provide a username and/or password to config the router.
Most routers allow you to open up ports for TCP, UDP or both and sometimes
both of them are referred to either as BOTH or IP. You may even have a list
of known applications, with their associated ports where you can just enable
them and the correct ports will be opened. All you have to provide beyond
that is the internal destination IP address. This is a dynamic modification
and generally does not require a reboot of the router.

Let me know if you need more help. I apologize for the delay in my response
but I'm having issues with VS.NET.
