Networking isn't my specialty, it's more like my weak spot. I came across this setup in which they are using a SonicWALL T100-W for their router/firewall, DNS/DHCP is handled by Server 2008R2 ADDS.
In the SonicWALL the WAN port X1 has a private IP address. I can see via the ARP cache within the SonicWALL the private IP belongs to a Juniper device.
They get their Internet through their VoIP provider.
I tried copying the port forwarding that already exists and works for port 443 which is used by Exchange 2010.
I even tried using the pubic server wizard to no avail. I want to know why the IP on the X1 port is a private IP address. Also I am trying to setup OpenVPN but like I said I can't hit it from the outside at all. I have a weird feeling there's something in front of that SonicWALL but I already contacted the ISP and they said they don't do any type of port forwarding so I am guessing it just passes the traffic directly onto the SonicWALL?
