Ports used during TopView operation
TopView can utilize a number of ports to perform its job, configure your firewall to allow communication over the following ports:
- Data source related ports
- Notification-related ports
- Email:
- Any ports used for SMTP
- POP, default 110, if incoming email retrieval is active
- IMAP ports, if incoming email retrieval is active
- Voice notification via VOIP:
- SIP port (TCP):
- The SIP port is where the VOIP client and server negotiate call details.
- 5060 TCP is the default for SIP communication (sometimes 5061). The SIP port can be configured in TopView.
- Media ports (UDP):
- For TopView, the media ports are where the VOIP call audio communication takes place.
- Default for TopView is 5000-30000. This range is configurable in TopView.
- Typical range is 10000-20000
- TopView allows the specification of a port range for RTP (media) communication using UDP (TopView defaults to: 5000-30000, but many VOIP systems recommend opening range 10000-20000). The media ports used during a call are negotiated by the client and server via SIP.
- Any ports configured in TopView for SNMP communication
- Remote Viewer ports
- Each Engine sets a port for Remote Viewer communication. This port is configured by the user.
- By default, TopView is set for Remote Viewer communication over port 6150, but you will need to open the Remote Viewer port in your firewall for each TopView Engine leveraging Remote Viewer.
- Backup / Failover ports (TopView 6.37 and later versions)
- The TCP Watchdog server can be hosted over a user-configured port.
