Why is my router double NAT?
Double NAT is when you connect your router behind another router creating two different private networks. Double NAT does not prevent your devices access to the internet but may cause problems with playing online games, opening a specific service port, connecting to a VPN tunnel, or visiting secure sites with SSL.
Does NAT require two routers?
Among other things, NAT allows the router to use a single WAN IP address (provided by the ISP) to deliver Internet access to many devices connected to it. That said, each network needs just one router, and, by default, a router always has its NAT turned on.
What does it mean when your router is doing double Nat?
If you see an address in the 10.x.x.x or 192.168.x.x range (both of which are private) it means that the device your router’s WAN port connects to is doing NAT, and hence, you’re dealing with double NAT. There are a several options available to correct — or circumvent — a double NAT situation.
How does nat work on a WAN network?
NAT ( Network Address Translation) allows your devices to share a single WAN IP address (provided by your Internet Service Provider) by changing the public IP address to a private IP address. This process also secures your network by blocking any direct access to your local IP address.
Where does a WAN port go on a router?
The router’s Wide Area Network ( WAN) port gets the public IP address, and PCs and other devices that are connected to LAN ports (or via Wi-Fi) become part of a private network, usually in the 192.168.x.x address range.
What’s the best way to do NAT on a router?
If you have a lot of ports to forward, doing them individually can get a bit cumbersome, so a simpler method is to configure the first NAT device to make your router’s IP address the DMZ.
