We are running SBS 2011 and we can't connect to the our RWW from the outside. We connect using http://remote.domainname.com/remote. It works internally, but not externally. The ports that are forwarded to the SBS box are: 443, 987, 80, 25. There's been no IP changes. Just suddenly stopped working.

First try Start > Run > iisreset

Any installed Updates?
Updates installed but pending reboot?

Alle services running? (start > run > services.msc)

I also would advice using https only with a valid CA signed certificate to better secure the communications. If you would login, for example, on an airport or hotel with a public wifi, your login details could be intercepted and thus give unwanted persons access to the server.

If it is working from within your LAN your services are running properly and you are facing a problem with either your firewall or you ISP DNS service.


Try to see if you can ping your external IP to access your server, if you don't get anything then check your router/firewall and make sure it forwards everything to the right server.

Last thing, check your server's anti-virus/firewall.

it would help us to find your error if you posted your domainname.
We can check external dns records to see what the issue might be

I strongly suggest that you turn off port forwarding for port 80 and require users to connect with https:// and not http://

Has this ever worked?

I did a check on the DNS and the remote.companyname.com is pointing to the correct IP address for the A record. This did work since we setup the server. Users just reported it stopped working yesterday. Not sure the last time they used it though.

No - mx records are pointing to hosted exchange server provider. Remote.companyname.com points to IP and I can get to that to login to the firewall. however remote.companyname.com/remote goes no where

I thought maybe it was because i had the management turned on on the external interface for the firewall, so i could get to it by external IP - so i turned that off, but no luck.

Ok. Found the issue. On the Sonicwall there is an address object that is referenced for the port forwarding. The IP address on that address object had change to 192.168.1.1 which is the firewall. It should have been 192.168.1.2 - which is the server. Thanks everyone.
