NAT loopback stopped working (RAX30)

[axaxax]

I have been happily using my RAX30 to access a server on my home network, but yesterday it stopped working.

I can access the service using a local IP address, but when I use its public domain name or my public IP, I get no response.

curl says:

connect to w.x.y.z port 80 failed: No route to host

It is the same on all machine in my house, but when I disconnect my phone from the wifi so it uses mobile data, the server works perfectly.

Does anyone have any ideas why?

I have tried:

* rebooting the router

* unplugging and re-plugging the router

* downgrading the firmware

but none of them help.

Thanks for your help!

Of course, as soon as I posted this I found the problem!

NAT loopback was working fine, but the local IP address of my service had changed, so my port forwarding rule was pointing to the wrong IP.

I have added an address reservation under LAN Setup to prevent this happening again.

Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
