Although PortaSwitch servers are based on the Oracle Linux OS which is designed for high security, it is still reasonable to consider external firewall for better system protection. If you want to position servers behind the firewall for some reason (e.g., your corporate network security policy demands this) follow the recommendations below.

General configuration advice

Link copied to clipboard
  • We suggest positioning all PortaSwitch servers into a dedicated network segment.
  • Interaction between PortaSwitch servers via a private network interface must not be blocked by a firewall.
  • Whatever configuration your private LAN segment has, internal communication between servers (via TCP port 22, etc.) must always be granted.
  • Do not configure a firewall between nodes of the cluster (e.g., PortaSIP cluster, etc.).
  • For PortaSwitch sites that span across geographically dispersed locations, all PortaSwitch servers must be connected via virtual or physical) Layer 2 connection(s) and all PortaSwitch servers should be configured as hosts within a single virtual (or physical) private network.

Ports to be opened

Link copied to clipboard

Logical components (e.g., Admin, Billing, Master DB, Replica DB, PortaSIP) are installed and operating on some hosts. This requires particular ports to be kept open on these hosts, depending on which components are running on each of them. To find out which open ports are required by each component, see the table below:
