This screenshot shows how the router is configured for port forwarding, so that I can use remote SSH (Secure Shell) on a server on the local network. Services like these sometimes require certain ports to be opened in the router’s firewall and directed to a particular computer or device on the network. This would include online gaming on computers or consoles, remote desktop into your computers, connecting to a VPN server, or accessing security camera feeds.

When there’s double NAT on your network, you might run into issues with services that require UPnP (Universal Plug-and-Play) support or manual port forwarding. But if there’s multiple Ethernet ports or if it supports Wi-Fi connections, it’s likely performing NAT and routing as well. If there’s only one Ethernet port, it’s likely a simple modem (aka a broadband gateway). If you’re unsure what the ISP has given you, take a look at the box. But most ISPs assume their customers don't have routers, however, so they’ll provide you with a combo device whether you want it or not.

Some ISPs install only a simple modem that lacks the NAT and routing functions, which eliminates the problem altogether. Having more than one NAT device usually happens when you connect your own router to a gateway installed by your internet service provider (ISP) that also includes the NAT and routing functions. So, it’s always a good idea to eliminate double NAT if you have it. But others can run into headaches with certain applications, services, and situations. Some users may never notice, making it a non-issue for them. Having more than one device performing NAT on a private network, however, can cause issues with that network.
In order for SkyBell to connect to these routers, the bands must be split to allow the two to broadcast on separate networks. Newer model wireless routers operate with the 2.4 GHz and 5 GHz bands broadcasting simultaneously.
However, SkyBell only connects to the 2.4 GHz frequency band. This allows SkyBell to connect to B-only, G-only, mixed BG, & mixed BGN networks.
SkyBell is equipped with an 802.11b/g/n wireless chip set.
