Hi Major,
I am aware of both my internal address (192 (not 198 - my error in my message).168.0.1 and my WAN (internet) IP of 168.103.108.211 . My understanding from our son, a software engineer, is that in the following modem instruction:
*************
Selecting Port Forwarding in the “Advanced Configuration” screen generates the
“Port Forwarding” screen. Port forwarding allows certain programs to bypass the
Gateway’s built-in firewall, allowing access to parts of the network (for hosting a
Web or ftp server, for example). To use port forwarding, enter the IP port range in
the “IP Port Range” text boxes. (If more than 10 ports are needed, Actiontec recommends
using DMZ Hosting. See “DMZ Hosting,” below, for more information.)
Choose the protocol type from the “Protocol” list box, then enter the IP address of
the computer on the network to be used as a host. Click Add. The forwarded ports
appear in the “List of Forwarded Ports” text box.
To remove forwarded ports, highlight them, then click Remove.
***********
... the address I should use - "ip address of the computer on the network" is the INTERNAL address of my pc (192.xx etc) and not the WAN/Internet IP address. Perhaps he is mistaken and I should use the WAN/Internet IP address.
I will try that next! Thanks for your reply.
