“Detect Network Settings” button gives problems on PBXs
I have some FreePBX all with: Asterisk Version: 13.13.1 FreePBX 13.0.197.22
The “Detect Network Settings” button no longer works on these PBXs.
It has been happening for a few days “maybe it’s more time but I recently realized it …”
Does anyone know of any changes that can cause this anomaly?
That said, I’ve experienced this with premises servers and I think it’s, to some degree, a firewall issue. For example, there are times I want to obtain the WAN address that my PBX is using so I will run a dig command:
But no results will populate, because I’m getting blocked. Whereas this issue never occurs for servers in the cloud.
What are you trying to accomplish? If it’s just a simple on prem config, I’d get your WAN address and subnets manually and enter them in.
If you’re trying to use a dynamic external address, purchase the module system admin pro and use the DDNS setting there. Of course, if you have your own, you can use that too. Only caveat is that you don’t want your firewall cutting you off.
I am using a raspberry behind nat, the firewall is written by me iptables and until today it had not given me problems and in any case disabling it the problem remains
