need to access a registered website through the modem/router
I had my modem set to a router with port forwarding for 443 and I could access a registered domain that I host. The router "expired", as it seems that Linksys routers do after 4-5 years. I decided to use the ATT Arris NVG589 as both a modem & router and it is working great. I have set a port forwarding rule for 443 (https) in NAT/Gaming but I still can't get to my website from outside the network. It is broadcast from a PC with a fixed IP allocation.
It worked great for years until I lost the Linksys router. I feel there is one more thing I need to do on the Arris modem/router. IP Passthrough? I know the port, so there's no need to do that. Any other suggestions? Thank you.
