Service Point port requirements:
| Source IP | Destination IP | Source Port | Destination Port | Protocol | Description |
|---|---|---|---|---|---|
| <Client IP> | <Service Point IP> | Ephemeral | 22 | TCP | Required for SSH access. |
| <Service Point IP> | <Namespace forwarder IP> | Ephemeral | 53 | UDP + TCP | Outbound DNS queries |
| <Client IP> | <Service Point> | Ephemeral | 53 | UDP + TCP | Inbound DNS queries |
| <Service Point IP> | <NTP Server IP> | Ephemeral | 123 | UDP | NTP synchronization. By default this will reach out to the

/api/v1/health |
| <Monitoring System IP> | <Service Point IP> | Ephemeral | 8083 | TCP | Service Point telemetry APIs |
| <Monitoring System IP> | <Service Point IP> | Ephemeral | 9222 | TCP | Telegraf service |
| <Monitoring System IP> | <Service Point IP> | ICMP | Pings |
Additionally, the Service Point uses the following ports for internal communication
between microservices.
