IP Blacklist - Allow List Clearing

[M140]

Hey!

We are experiencing really odd issue that is occurring across several installs of 3CX, all on the latest software, installed via the PBX express on to 1and1's cloud.

We have allowed our site IP addresses to the IP Blacklist section under 'Allow' however we have found that list is empty the next day. This has happened on a few installs at different times, enough for us to know we are not going crazy. It is not always 24 hours, some lists have been populated for 2/3 months before clearing. We have specifically inputted the addresses rather than altering a 'deny' to an 'allow'.

Does anyone have a suggestion?

Sounds odd.

Is OS up to date?

If you're manually adding IP's to the blacklist why arent you doing this on your firewall?

Yes the OS is up to date,

The firewall isn't blocking the requests, 3CX was. We noticed as 3CX then blacklisted a couple sites for failed authentications. Our firewalls are fine.

I meant that your firewall should be blocking these IP addresses not 3CX.

If you're taking the time to add IP addresses to block to 3CX, you should do it on your firewall.
