Hello Everyone "[Smile]"

I am running a Exchange 2003 server on my network and want to use Outlook Web Access when I am out of the office.

I have an ADSL router on my network for the internet, I do NOT have IIS or anything on the server.

What port/s do I need to open on the ADSL router so that I can use Outlook Web Access?

Thanks
-Mike

Hi Mike,

Depends on how you set it up. You should be using SSL to SSL bridging. If you're using an ISA firewall, check out www.isaserver.org and look for the ISA 2000 Exchnage kit for all the complete step by step details on how to set it up.

HTH,
Tom

Hi

IIS is requiered to run Exchange OWA because it is a website.
I guess owa works from your local network.

OWA runs as a standard webpage so you just need to open TCP port 80 to your Exchange server if you don't want to use SSL.

Ans if you wan't to use SSL you need to open port 443 to your Exchange server.

Exchange 2003 can't be installed if the respective server isn't already running IIS, so you do have a webserver running.

Did you from an internal client or the Exchange server itself try to open Internet Explorer and type:

http://servername_or_IP/exchange

This will let you connect to your mailbox using Outlook Web Access (OWA). When you have verified this is possible, you need to open the respective ports in your firewall/router which would be port 80/TCP (HTTP) and/or port 443/TCP (HTTPS), if the Exchange server doesn't have a public IP address you even need to create a NAT rule in the router. When this step is completed you should be able to connect from an external client by typing:

http://public_IP/exchange

Then you might want to create an A record (people often call this record mail or similar) on the external DNS server hosting your domain name (typically your ISP), this will make it possible to connect by typing:

http://mail.domain.com/exchange

Finally you should without a question implement SSL as all communications between your OWA clients and the Exchange Server otherwise will be unencrypted (even the username/password handshakes), for a step by step guide on how to implement SSL see:
