Change External IP Address 3cx On Premise

[Alle CTEC]

I migrated the 3cx public IP address but the ..3cx.it record does not update and remains associated with the old IP

You should flip your network setting to dynamic temporarily, refresh your license key and then change it back to static once its updated.

 

[PaulEmous]

It takes time for the FQDN to be updated. (Dynanic)

Please note that the TTL of the FQDN is related to the license that you have:

1. Standard & Pro->6 hrs
2. Enterprise->5 min

Custom FQD->Manage yourself
Although I have rarely seen more than 10min of propagation delay

See @ChrisC_3CX post in thread 'IP change' for the good procedure

I have kept the dynamic update for more than 48 hours but the record does not change

 

[Alle CTEC]

I noticed that in the dashboard when I set dynamic it remains in detecting?

I noticed that in the dashboard when I set dynamic it remains in detecting?

what is the pbx version? is it running version 18.0.8.939?

set dynamic ip within the Network menu, then restar the 3cxdatabase server. The pbx must be running version 18.0.8.939

 

[Alle CTEC]

Yes version is 18.0 (Build 939)

I have restart the service 3CX PhoneSystem Database Server and 3CX PhoneSystem 01 System Server

I also restarted the 3cx, but it doesn't update my record and it remains in detecting obviously I checked outgoing I surf without restrictions with the new public IP

The record is old domain 3cx.it

If 3CX is installed on Linux... (and assuming that CURL is not installed)
Run this SSH command:

wget -O temp_ip.txt https://discoverv4.3cx.com/getip && clear && echo && echo "Your public IP is :" && cat temp_ip.txt && echo && echo && rm temp_ip.txt

The displayed IP address is the one detected by 3CX.


If it's on Windows,Open a web page on your Windows server and go to:
https://discoverv4.3cx.com/getip

The displayed IP address is the one detected by 3CX.

 

[Alle CTEC]

I ran the test, the IP address is correct but it is not changed, the domain is 3cx.it and more than 24 hours have passed

On the dashboard ipv4 is in detecting

 

[Guillaume Bourgeois]

Your firewall probably blocks access to stun.3cx.com
In any case.. Set your new iP in “Static iP (in 3CX Settings) … and restart services..

check propagation ;

Even though the traffic to stun.3cx.com was properly opened. I set the new IP, restarted the services and the record was automatically generated with the new IP address, thank you very much

Seize the opportunity to run a new 3CX Firewall Checker test to confirm that the network is configured properly.
