Ports Used by TimeIPS



On-site TimeIPS servers communicate via TCP/IP to update software, keep time synchronized and provide diagnostic functions. Listed below are the remote IP addresses and ports used. Standard firewall/router configurations usually allow access to external sites without any special configuration.  In locations with extremely tight network security, access to external IP addresses and ports may be limited to a special "whitelist" of known and authorized remote systems.  If this is the case for you, then please allow access to each of the items on the list that follows.  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, the ports and IP addresses simply require that the port be open to allow TCP/IP traffic.  TimeIPS servers DO NOT require port forwarding rules or any access from the outside to your internal network.

These ports need to be open to allow traffic out to the Internet.



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.
