My configuration is router isp ==> bare metal router ==> nethserver ==> LAN

Everything works fine last week but now not. If any one can help I appreciate.

Hi

Do I understand this in that you’re not using Double-NAT here, but Triple-NAT?
That could be part of the issues, also depending on the IPs/Networks used in each of the three networks…

A bit more information may help here…
What are you using as DNS?
Do you get a correct DNS resolution for zoom.us? (Verify eg using a mobile connection and nslookup or dig, whatever you prefer…).

Also, this “bare metal router” entails a very wide range of devices, from a switch to something like OPNsense/PFsense or OpenWRT - or a simple Debian running as router wirh 2 NICs…

More Info !!!

I’d say offhand DNS is your primary issue…

My 2 cents

Thanks Andy, the result of nslookup is:
