Solved Firewall configuration: Which DNS names?

[Steffen Maier]

Hello,

I would like to very strictly confiure my firewall.
Which DNS names does 3cx need to contact?

Like updates.3cx.com, downloads.3cx.com or similar for update traffic and or other services?

Wildcards are not possible (*.3cx.com).


Thank you,
Steffen Maier

Hello @Steffen Maier

The PBX will need to communicate with activation.3cx.com, downloads.3cx.com, webmeeting.3cx.net and the MCU you will use for webmeeting found under settings / Conferencing Settings.

Hello,

thanks, but updates still cannot be downloaded.
It is connecting to
35.201.76.132 which is non of the mentioned ones.

Try adding downloads-global.3cx.com and let us know if that worked.

That works, thanks
