My setup.

SBS 2003 Exchange Server - IP 10.0.0.3

Windows 2003 Files/Web Server - IP: 10.0.0.27

SonicWall Firewall : IP 10.0.0.1

I have my DNS records for mail(A,MX,PTR) pointing to my static IP address which hit's my firewall and routes traffic (port) to my Exchange Server. This works. mail.XXXXXXXXX.com

I have my DNS records for Web (Http/Https) pointing to my Exchange Server and File/Web Server.

Https - Points to my Exchange Server for accessing webmail. https://webmail.XXXXXXX.com/exchange

Http - Points to my File/Web Server for accessing my Intranet. http://webdesk.XXXXXXX.com

My problems.

I'm able to connect outlook to the exchange server while inside the network but, outside POP doesn't work.

I'm able to connect to https://webmail.XXXXXXXX.com/exchange from outside the network but, have to enter the IP of the server to enable webmail to work when I'm inside the network. https://10.0.0.3/exchange

I'm unable to connect to my webmail unless I put the "/exchange" at the end of the URL.

What I want to be able to do inside or/outside the network.

1) Connect to Webmail (my exchange server) using this address http://webmail.xxxxxxxxx.com

2) Connect to my Intranet (File/Web server) using this address http://webdesk.xxxxxxxxx.com

3) Have POP email work.

4) Have Https reserver for managing my firewall. (this was working until I had to use https for accessing webmail).

Hope someone can help. I think this is some pretty minor configuration that I've over looked but, would like some advice either way.

I'm sure I can figure this out myself but, thought I would see if someone can help shorten my trial and error time.

Thx

Hi,

You should be able to do (1) & (2) by modifying the rule on the SonicWALL to allow HTTPS traffic from * (not just WAN) to 10.0.0.3 & similarly for HTTP traffic to your other server. (you should already be able to access OWA using https://localservername/exchange)

The caveat here is that you will need to type in the /exchange at the end of the URL. If you don't want to do that (this is pretty normal!) then you'll need to allow access to the default website from the internet (use the CEICW in SBS for this) and put a redirect in there to point to /exchange. Perhaps you can do this with IIS host headers as well, but I'm not sure.

(3) If you're using XP SP2 & Outlook 2003 you don't need to use POP for mail when outside the network. Use RPC over HTTPS instead - it gives you full functionality. Have a look at http://www.amset.info/exchange/rpc-http.asp

(4) This can only work if you have multiple IP addresses. Then you can use one for your firewall, and use 1 for your server(s). If not, then you're out of luck because logically you can't have two different hosts on the same protocol at the same IP...
