SBS 2011 Remote Web Access continually goes offline

Constantly my remote web access to my SBS server goes down. I have to restore it by running the Set up my Internet Address Wizard. This fixes the symptom. I don't know what the problem is.

SBS 2011 on network with 13 Win7 Pro workstations.

How do you know that RWW is down? what are the errors? does OWA go down at the same time?

down...? please give a specific error so we can help you better or a screenshot.

if its an access issue next time you experience the problem reset the router, if it helps I'd start with the router.

I'm sorry - down as in I attempt to log onto the https://remote.****.com remote website through SBS and I cannot get the site to connect. It's accessible throughout the internal network but not over the internet to a computer not connected to the SBS network.

I hope that clears it up.

This happens frequently, and like I said, the solution 9 times out of 10 has been to run the Setting Up your Internet Address wizard.

1) are you using the self-signed cert or CA?
2) ensure appropriate ports are NATed and allowed through the firewall: 25, 443, 987, possibly 80 although i do not recommend it
3) verify you only have 1 NIC enabled on the server

Beyond that, what errors are you getting when trying to connect on the remote computer? is there anything in SBS logs? firewall logs?

I use the self-signed cert. as far as the ports, why would the allow the RWA site up one day and down the next? that doesn't make sense. but I will look into the ports in IIS. I'll also look at 1 NIC or 2. What's the difference, why would that make the site sometimes up/sometimes down?

thanks in advance guys and girls
