A bit of a lazy approach, but if you have a personal firewall on that PC you might be able to get away with it. Thus, all outside->inside initiated traffic will be forwarded to that PC. You can also expose that PC to all external access by specifying its IP address when using the Basic -> DMZ settings on your modem. This way, you are limiting the attack surface of your network, and only exposing that one inside PC and only on specific ports. You can either hard-code it on your PC or you can create a DHCP reservation for that PC on your modem so that, despite the fact that it's a dynamically obtained IP address, you get the same address every time. For this to work properly you will need to define a static IP address for that PC, which in your case is your gaming rig. For example, if someone is trying to communicate with your LAN connected device (aka inside PC) from the Internet on port 443 (secure HTTP) then you would forward all traffic on the public (aka WAN) port 443 to private port 443 on IP address. If port-forwarding (and I really believe this is what you mean, then essentially all you're doing is selectively forwarding traffic that hits those ranges of port numbers on your WAN side to a specific device on the LAN side. That said, are you talking about port-forwarding or port-triggering? Two different things. If you'd lay my schematic next to the sheet music/book your holding, you should be able to see how the song goes. I recognize that there are reasons for having different firewall settings (max, minimum, custom.) but these setting aren't very granular.Īt a certain point you have to balance the likelihood of someone compromising your security vs the vulnerability. My bad: I meant Da Coda and your book is correct. Have you rebooted the modem after applying and saving the you can't have port-forwarding w/o UPnP then you don't have much of a choice, do you? That said, UPnP is not (read: never!) a good option for a commercial firewall in a business context but I wouldn't be particularly worried about using it in my home.Have you spoken with LoL support to troubleshoot the port forwarding issue?.Are you using your own router in addition to the CODA modem?.Can you confirm which firmware version your modem is running?.Is UPnP enabled or disabled on your modem?.To best assist though with removing the requirement of port forwarding, can you confirm the following for us? We'll be happy though to assist in any way we can. I haven't personally had to apply port forwarding for LoL, so for specifics regarding their required ports, and port forwarding settings, you may need to contact their support directly. It's admittedly strange to hear someone requiring port forwarding for League of Legends! UPnP should be enabled on your modem allowing for optimal connectivity to the majority of major gaming ingest servers, including Riot's,so it's concerning for sure if that's not happening.
