External IP address with router

Hi folks,
I have a Linksys router that my NTL broadband goes into before being split
out to 3 PC's. I have IIS running on my PC, and want to know how I can let
people in the outside world view my pages being served, i.e. how do I find
out what my PC's IP address is with a router in place?

unless NTL have given you an extra IP address then only the router
will have a public IP address. You need to get the router to "port
forward" incoming connections on the port concerned to the relevant
PC, using the IP address of the router ie 213.107.142.89

Is the weather nice in 'Uddersfield today ?

There will be a web page on your router which is only accessible from your
side of the router.
If you browse to that then there will be various configuration screens.
In there you can find your public IP address , and also set up a mapping so
that web requests sent to the public IP address are forwarded to your
machine running IIS on the inside.

Sorry I can't be more specific , but you will need to check the manual for
your router for the exact details of how to do this.

Could the OP set-up a DMZ to the IIS (as long as it has it's own FW)?

Another probem might be that his IP address is probably 'dynamic'
(all be it that it stays the same for long periods), I also *think*
domestic uers have to offer 'services' (HTTP / FTP etc) via the use of
a password type system (ie not an 'open' public server) or some such?

All from memory and I *am* getting old ... ;-)

T i m

Set up a port forward on the router, linking port 80 (HTTP) to port 80 of
your internal IIS server.

You will also need to setup a dynamic DNS system, since NTL only gives one
IP (which will be assigned to the router) and will be assigned to the
router. It is technically dynamic, so is likely to change, albeit not very
often. I've used www.gotdns.com and no-ip.com in the past and they've
worked fine, just use a Win32 client to update the IP.

Good luck

It is almost certain that the IP address of your PC will not be visible
from the other (internet) side of your router. You need to change your
router config to allow it to perform port-forwarding of port 80 (http)(+
443 if you are using https) from your PC through the router and out onto
the internet. As I don't have a linksys router I can't give you the
specific details but you will have to get your router config changed, it's
not as simple as finding the PC IP address and letting people know what
that is.
