This will disable the gateway’s NAT, firewall, and DHCP functions and reduce it to a simple internet modem. If you’d like to keep your router, see if you can put the ISP’s gateway into bridge or passthrough mode. If you’re a power-user and you can’t part with your fancier router, then this option probably isn’t for you. One simple way is to unplug any additional router and only use your ISP’s gateway. If you’ve confirmed you have double NAT, there are ways to fix it. More evidence of a double NAT situation: My router’s WAN IP address is private, not public. Addresses outside of these ranges would be public (internet) addresses.

Or sometimes, if the ISP installers are knowledgeable, they might fix it when they come out to install the gateway and see that you have your own router.įor the two ways I’ll show you how to detect a double NAT situation, you’ll need to check your IP addresses and know if they’re private or public. Sometimes gateways will detect double NAT and automatically fix the issue for you. I already mentioned how to quickly tell if an ISP’s gateway has NAT and routing capabilities, but you might also want to see if double NAT is actually happening before spending time on the issue. This screenshot shows my router’s QoS (Quality of Service) controls, which I’ve configured to assign VoIP (Voice over Internet Protocol) top priority. This is especially the case if you have devices connected to both routers, both of which have different QoS controls.

It might only forward traffic to computers and devices directly connected to that first router, which could be either a wireless or wired connection.ĭouble NAT can also complicate any manual or automatic quality-of-service (QoS) controls that prioritize traffic on your internal network to ensure lag-sensitive traffic (gaming, voice, or video) is given higher priority than data associated with file transers. Or even if the first router has the port forwards, it can’t forward the traffic to a device that’s connected to the second router. The problem with double NAT is that if the first router on your network doesn’t have the port forwards configured, incoming traffic will stop there even if you have the port forwards configured on the second router. I can’t do that if my gateway is also performing NAT (network address translation). This screenshot shows how I’ve configured my router for port forwarding, so that I can use remote SSH (Secure Shell) on a server on my 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.
