Dell Sonicwall TZ 500 SSLVPN not connecting from outside

We have  Dell Sonicwall TZ 500 firmware ver.6.2:
I configured an SSLVPN according Dell documentation.  I can connect to the inside address: https://10.1.1.1/4433 and the netextender page is available.  However, when we login to the outside address https://x.x.x.x/4433, we get "Page cannot be displayed".
I am thinking it is related to port 4433 not being nat'd to the SSLVPN service but the service group is there and the NAT rules are there.
Anyone have any thoughts on where to look?

Port 4433 is not a standard SSL port (unless if there is a port forwarding rule to forward from 4433 to 443).  It should be 443 then when you use the URL "HTTPS://x.x.x.x" it will automatically connect using that port.

If you plan to use custom port 4433 then try typing in "HTTP://x.x.x.x:4433"

When I goto the custom outside port http://x.x.x.x:4433, it still comes up "Page cannot be displayed".
I attempting to connect from a remote PC outside the network.  Again, when I connect from inside the network Netextender comes up fine.

Hi mgchar7,

Port 4433 is the correct port and the default port in SonicOS 5.6.x.x onwards. You need to make sure nothing else is running on that port. For example, if you have remote management setup and 443 open you will have to change the remote management port to something else...some people make the mistake of using 4433 not realizing its the default SSL-VPN port too. Also, make sure you have not locked down the Source in the Access Rules too.

What document are you referring to...please provide the link.

Let me know if you have any other questions!

Thanks bluestreet,
Bingo, thanks so much, changing the SSL port for remote management fixed WAN access to the SSL splash page.  It is working now!
Thank you very much for your help!
