Resolution

Ensure that the endpoint is connected to a network that allows VPN connections or UDP ports 500 and 4500 are allowed at the firewall level.

  • Verify that these ports are allowed, check the endpoint's software firewall, as well as the network's edge firewall.
  • UDP ping to 500 and 4500 ports can be run to verify connectivity. Tools such as PsPing can be used and verify router not blocking requests.
  • Wireshark can also be used to capture and trace UDP connections. Capture filters: udp port 500 and udp port 4500
