DNS Question

[Rene1024]

Hello,

I have DNS running on a Windows 2003 server, I also have an Exchange 2003 server that is working fine for the most part.

Here's my problem:

Whenever I try to access my Outlook web access from within the LAN I open my browser and type mail.mydomain.com, but instead of going to my exchange server my browser takes me to my firewall's management conse login.

I would like to create a DNS host or alias that when someone in my LAN types mail.mydomain.com it takes them to my exchange server (192.168.1.10)

Thanks for your help.

Rgds,

Rene

Just use the address

http://servername/exchange

from inside the domain.

I hope you find this post helpful.

Markdmac is correct. mail.yourdomain.com is pointing to your public static ip. This goes to your firewall then I assume you have things NAT.

From the outside if you would like create a new host name record with your ISP. webmail.yourdomain.com. Assign an IP then NAT it on your firewall.

The request is made webmail.yourdomain.com/exchange (123.123.123.123 or whatever ip range is) gets forwarded to your firewall. You will then have 123.123.123.123 NAT'ed to your exchange server port 80 192.168.1.x

That should do it.

Thanks for the replies,

The reason why I'm trying to make this happen is because I have some traveling users that need to use RPC over HTTP.

When I set up the Outlook client on their notebooks I have to adjust the settings to point to

https://mail.mydomain.com

which works great outside the LAN, but once the users connects to my LAN they're not able to connect to the exchange server and I was trying to avoid setting up two profiles for each user.

Please let me know this is possible.

Just create an alias in DNS called 'mail' - presuming that you are running your internal network with the same domain name as your external name.

Good Luck,

Hi Steve,

Unfortunatel, I'm using diferent names.

I was hopping that I could create a host, alias or MX record on my DNS server and force the connections to the Exchange server's internal IP address.

Can this be done?

Stevehewitt knows whats up. In DNS management under your forward lookup Zone, right click the Zone, and create an Alias named 'mail' then point it to the 'servername' of the server you want it to goto. You will most likely have to flush your DNS

 

[Davetoo]

Since the internal domain is different, you'll have to setup a new forward zone for the external name, then include a mail Alias as well as a

http://www alias

and any other alias available on your external name (ftp, etc).

The problem then is anytime your external domain changes, say to a new web server, etc., you'll have to update your DNS to reflect that change, otherwise inside users will get directed to the old name.

Thanks for all the suggestions,

I created the alias like you suggested, flushed the DNS and it still did not work.

Creating a new zone like Davetoo suggested sounds too advanced for me, so I think I'll just have my traveling users work with two Outlook profiles for now.

Thanks again for all your input and if think of anything please let me know.

Rgds.
