Ports Used by TimeIPS
Your TimeIPS system requires the ability to communicate via TCP/IP over several ports to be able to successfully update its software and provide other diagnostic information. Listed below are the ports required to be open to allow the TimeIPS network traffic to reach the public Internet and contact our servers. Different routers require different configuration techniques to allow these ports to be open. Please check with your router hardware provider for specific instructions on how to configure your specific router. Please note, port-forwarding is not required, simply the port being open to allow TCP/IP traffic.
Firewall/Router Ports (TCP outgoing) that need to be opened:
These ports need to be open to allow traffic out to the Internet.
- 443 (HTTPS) to 75.48.191.220 and 75.48.191.221 Required to authenticate for updates and off-site backups.
- 443 (HTTPS) to 75.48.191.219 Required to download updates.
- 80 (HTTP) to 75.48.191.220 Required to authenticate IPSVOIP devices.
- 80 (HTTP) to timeips.com (65.254.250.105) Recommended for faster update speeds.
- 53 (DNS) Required for name resolution.
- 25 (SMTP) Required for email reports and messages. NOTE: Many ISPs block port 25. If this is the case for you, use your ISP's mail server, or configure email with a different port in TimeIPS and on your mail server and open the corresponding port on your firewall.
- 123 (NTP) Recommended for time synchronization. Note: NTP requires UDP, not TCP.
Firewall/Router Ports (TCP incoming) that need to be forwarded:
If you have clocks or users outside your local network, these ports need to be "port-forwarded" in your router or firewall.
- Client version 3.x and older (TimeIPS 1.5 and older):
3306 (Clock connectivity) Required for clock to master connectivity. Port forward required for WAN clocks.
- Client version 4.x (TimeIPS 1.6 up to 1.6.29):
9999 (Clock connectivity) Required for clock to master connectivity. Port forward required for WAN clocks.
- Client version 5.x (TimeIPS 1.6.30 and later):
80 (Clock connectivity) Required for clock to master connectivity. Port forward required for WAN clocks.
- Client version 5.x (TimeIPS 1.6.44 and later):
User specified port for clock connectivity can be set in System Administration->System Settings in the Network Configuration area in the Clock Access Port field.
- 80 (HTTP) If using port forwarding for remote access to administrative pages, forward incoming HTTP traffic to your master station's LAN IP to port 80.
