Configuring Linux Firewall Rules
After having successfully installed PortSIP PBX, the PortSIP PBX ports have been opened with the Linux firewall. Note, PortSIP PBX enabled the firewalld by default, if you using Debian/Ubuntu, the UFW will be disabled automatically by PortSIP PBX. If your server has a firewall that is blocking the ports, you must open the below ports in order to make the PortSIP PBX working properly.
UDP ports: 45000– 65000, 25000- 34999 . These ports are used for the RTP sessions.
TCP: 8899– 8900、8887-8888、8881-8885. These ports are used for Server control and WebRTC client.
UDP: 5060. This is the default UDP transport for SIP communications (to send and receive SIP signaling).
TCP: 5065. This is the default WSS transport for SIP communications in the browser (to send and receive SIP signaling).
You also need to open the port that you are using for adding new transport:
Assume you have added a TLS transport on port 5063, you must open TCP port 5063 in your Linux firewall and
Assume you have added a TCP transport on port 5061, you must open TCP port 5061 in your Linux firewall
Assume you have added a UDP transport on port 5068, you must open UDP port 5068 in your Linux firewall
Important: if you running the PBX on the cloud platform such as AWS, and the cloud platform has the firewall itself, you MUST open the ports on the cloud platform firewall too.
