Hello,
We have our 3CX server hosted on an Amazon instance. We have recently received several emails from 3CX about IP making too many login attempts so we've decided to lock down the firewall to our single office IP.
I have found the below list of ports to open but the firewall checker still fails. Are there any additional ports to open? Does any one have any experience locking down the firewall to a 3CX server?
TCP 5000 or 80 v14: This port can be configured when Webserver is Abyss. On IIS it is fixed to 80
TCP 5001 or 443 v14: This port can be configured when Webserver is Abyss. On IIS it is fixed to 443
UDP & TCP 5060 3CX Phone System (SIP)
TCP 5061 3CX Phone System (SecureSIP) TLS
UDP & TCP 5090 3CX Tunnel Protocol Service Listener
UDP 9000-9255 (default) 3CX Media Server (RTP) – WAN audio/video/t38 streams
UDP 9256-9500 (default) External media transmission for 3CX WebRTC
