DNS Question 1

[lanwan]

I have a network question. It should be easier to describe my problem in steps:

1. I am hosting web servers on my network.
2. My internal network is NAT translated. (192.168.1.x)
3. I have never been able to access my own sites with "outside" domain
names. I must use the NAT ip address to access my website.

I would like to be able to access my own internal sites without using
IP addresses. Do you know of any fixes that would help? Do you have
any network suggestions or steps that can be taken by me to solve the
problem?

Thanks

Get a DNS server internally to point to the sites' internal IP addresses, or use the local hosts file on the machine you are trying to access from.

Assuming your using DSL ar a cable connection, running a internal DNS server will not solve your problem. The only legal internet IP address that you get is that one on the outside of your NAT device, provided by your ISP.

A solution would be using dymanic DNS (example:

http://www/dyndns.com)

This is a possibility to link yopu ISP's address to an URL (DNS) name like

http://www.mysite.com.

It takes a little effort toset up dynamic dns, but when it is working, it works fine. Even if your ISP changes your IP address (cable providers do that, DSL providers not always) the dyndns utility will update the dns entry and people can still reach you by typing in the URL.

The story above is only for DSL/Cable connections.

Hope you can do something with this info
Good luck

Lanwan,
As long as your webserver is part of your internal network then follow serbtastics advice and that will take care of the problem.

Thanks, serbtastics advice on editing the hosts file was the fix.

Running an internal DNS server on his network WOULD solve the problem. Then all he would need to do is create A records pointing to his host's internal IP address.

I have DNS running on our w2k server,it forwards requests for our web address to our ISPs name server, how do I create a record in DNS so that it will point to the internal address of our webserver instead?

 

[wbg34]

Open open win2k DNS expand server, expand forward lookup zones, expand domain. Right Click on the domain folder and select new host. Enter

the name and your internal ip address in address.
