OWA ports required using 2820n was created by nelvon
I Have just setup a 2820n to connect to our new BT broadband line with a static IP.

We are using SBS2003 and ran VPN connections, Remote Web Workplace and Outlook Web Access thorugh our old Watchgaurd connection.

We used to just type in:

http://old_IP_address/exchange
http://old_IP_address/remote

to get either RWW and OWA respectively

I have enabled open ports using:
NAT >> Open Ports >> Edit Open Ports

And opened 443 (RDP), 4125 (RWW), 1723 (VPN) and 25 (SMTP)
All pointing at the SBS server IP.

Our e-mail and Blackberries work fine, but when I enter:
http://our_new_IP/remote
http://our_new_IP/exchange

I get a 404 Not Found!!! web page error for both

Can anyone tell me what I am missing?
Also should I open 8080 the HTTP protocol used by the server?

Thanks for your time

There are a couple of issues here:

1. You need not, indeed should not, allow any HTTP access to your SBS. Use secure HTTPS exclusively.

2. The 404 error is probably because you have remote management enabled for your 2820, so all http:// URLs are handled by it. Turn off remote management on your 2820 (or at least change the remote management ports used by it - I have found this flakey, though). You can so this via System Maintenance -> Management.

Thanks cocospm
turning off remote management solved the problem and we now have OWA and VPN and FTP.

I do see a need for remote management of the router though.
How would I accomplish this?

Thanks again

You could try enabling secure (https) remote management on a port other than 443, to see if that still allows RWW and OWA to pass through. As I said, though, my experience is that sometimes ends up interfering with 443 pass throuh on the 2820 - it might depend on which version of the 2820 firmware you have. I gave up on that a long time ago, and haven't tested it with the latest firmware. You could always RWW through to the SBS or a workstation and manage the 2820 from there. That's what I do.

Thanks for the tip.
Just tried RWW and then back to the Draytek - works fine.
With everything else working I will carry on with this setup.

Thanks again
