I have ultra VNC running now behind a Sonicwall TZ170. I have the ports 5800 and 5900 opened up to the PC behind the Sonicwall, but from outside it I can't get in, from inside the VPN LAN it works using the dns.org address, local LAN IP, or public IP. But can't get in from the outside WAN. Any help out there please...
Jim :x

From what I know - I only set up the TCP ports to work and it did on local firewall and the router.
What I think is happening from your internal network your router is smart enough to realize that the destination and source is the same network on the LAN side so its not actually testing out your port forwarding rules.
Go to any site you wish to use that checks ports on your network.
e.g. https://grc.com/x/ne.dll?bh0bkyd2
see if they see it as FAILED - something responded - RED.. this means the port is actually open and someone is responding on your network.
