Hi,

I have two webservers running on seperate machines on my network. What do i
need to do to my dns settings on my 2k3 server to enable my to put the
machine name in front of my no-ip dynamic dns updater thingy and access
whichever webserver i want, from an external internet machine?

eg.

http://computer1.mydomain.no-ip.com
http://computer2.mydomain.no-ip.com

i have dns forwarders set up, and when i look in the list of my domain in
forward lookup zones i see all computers as Hosts(A) and their IP.

Thanks in advance

Andrew
 
Hi,

All you need to do is create a new host record and input
the name of the server as the host name (just the host
name, do not add no-ip.com dns will append this for you)
and then enter the IP address of the server your going to
use. Then you should be able to access the web site using
the Http://hostname.no-ip.com address. This is how I have
my Internal web site setup. This should work as well for
external sites, but im not 100% sure because i do not have
external internet connectivity on my domain.

Your question is nearly incomprehensible; if you don't receive a suitable
answer
try rewording and resubmitting it. If it is an English issue try to find
someone to
assist you in formulating it.

As with any DNS record you need to add the server name to the appropriate
zone, usually as an A (or HOST) record.

So you add Computer1 to the zone mydomain.no-ip.com.
 
I have two machines on a network, connected logically to a 2k3 server. They
are all physically connected to a router, to the internet. The server
manages files and DNS only. The router manages DHCP.

I am running a webserver on the two client machines.
I have a dynamic dns updater running on the server pointing
mydomain.no-ip.com to my ip address, eg. 81.102.123.254

If, in the router, I set port 80 to forward to 192.168.0.1 (client 1), then
accessing mydomain.no-ip.com from a browser, shows the webserver on computer
1. making 80 forward to .2 (client2) shows the server on computer 2.

How can I make it so that if i browse to computer1.mydomain.no-ip.com it
loads computer1, and if I browse to computer2.mydomain.no-ip.com, it loads
computer2? I dont only want to use port 80 for this, i also want to use
telnet and ftp on the seperate machines.

Sorry for any confusion

Thanks for any help

It usually works better if you describe your PROBLEM first and then give
the details....

Is this the IP of the Router? If so there is no way to distinguish the
TWO servers except to use multiple ports (host headers won't work here,
and you would only have one IP address.)

You are confusing the issue of multiple web sites with routing and port
mapping.

Simplify by thinking of these (at least somewhat) separately and the problem
gets
much easier.
How can I make it so that if i browse to computer1.mydomain.no-ip.com it
loads computer1, and if I browse to computer2.mydomain.no-ip.com, it loads
computer2? I dont only want to use port 80 for this, i also want to use

You cannot unless you have more than one IP address OR you map by port.

Since multiple IP address are easy and you apparenlty don't have that, let's
talk
about port mapping.

If you map port 8080 on the Router to address 1 and port 8888 to address 2,
then you can easily register the two DNS names to these addresses but there
is
NO WAY to include the port for general services such as Web, telnet, ftp.

Therefore your clients will need to connect using the equivalent of
ADDRESS1:8080
or ADDRESS2:8080.

This is generally an unsatisfying solution.

Why not just put BOTH Web sites on one machine? Then differentiate by
"host headers".
This only works (generally) for web services though.

You really need multiple PUBLIC IP addresses on the router to make this work
the way
you likely wish it to work.

Keep it simple.
