I'm trying to setup a Web/FTP site at a remote office that doesn't have a static IP from the ISP. We've setup a DDNS for the remote office and configured the SonicWall TZ 105 there so that our VPN will work. However, when I try to duplicate the NAT setup we have in our main office (which does have a static IP) to forward all web and FTP traffic to a the server there, all the other computer there can't get out to the internet. All the help I find when searching the internet is for older version of the firmware and not very helpful. I need to know what to put in the Translated Source and Original Source as that is supposed to be the public IP address. I want to put the DDNS name there, but the SonicWall doesn't let me create an Address Object with a DNS name.
