Alternative routing around NAT setup
Alternative routing around NAT setup
Hello everyone, I recently set up an old laptop with Ubuntu and Pi-Hole. The installation was straightforward. But Telstra, one of the biggest ISPs, has turned off NAT loopback on their modems. This prevents me from using Pi-Hole as my DNS server, so I can’t reach local servers like Minecraft or CS:GO. I also can’t access websites hosted on my network from another computer. There’s a lot of frustration here. Do you have any suggestions to bypass this issue without buying another router with loopback support? Any advice would be greatly appreciated!
To enable WAN access for the local network, it makes sense since your configuration typically handles things locally. Virtual machines rely on this connection to access the internet through their host.
It's not referred to as NAT loopback, it's known as NAT hairpinning. It isn't turned off, probably the device can't handle it. Hairpinning is meant for particular situations. Why can't you reach your services from within your local network? If you're on your LAN, you shouldn't need to use public access. You don't require hairpinning unless you're specifically trying to connect through the LAN.
Are you sure? I thought loopback was necessary for LAN access. With the Telstra Arcadyan, I can connect from a mobile hotspot instead.
