UDP ports

For the 4G LTE CellSpot to work, UDP ports 123, 500, and 4500 must be open. Customers must contact their ISP and ask if these ports are blocked. If these ports are actively blocked by the ISP, customers must request their ISP unblock these ports.

 

  • No port forwarding is needed.
  • Below is what these ports are used for:
    • UDP 123: Syncing clocks
    • UDP 500/4500: VPN or IPSec tunnels, business application
  • Have customer verify with their ISP that their connection meets these requirements:
    • Ping / latency: 200 ms or less
    • Upload: 0.5 Mbps or more
    • Download: 2 Mbps or more
    • Bridge mode: enabled

  • If the ISP confirms the ports are open, have customer request to add the CellSpot to a DMZ.

 

Verify correct ports are open

For the 4G LTE CellSpot to connect to T-Mobile's network, ports 123, 500, 4500 must be unblocked. Follow the steps below to determine if the ports are unblocked. Port 80 is used as an example for the screenshots. You will need to substitute ports 123, 500, and 4500 for 80 where shown.
