The following ports must be configured for **public internet access** unless otherwise stated:

| Port | Protocol | Direction | Description |
| ------- | -------- | -------------- | ------------------------------------- |
| `50111` | TCP | Ingress/Egress | Gossip protocol |
| `50211` | TCP | Ingress/Egress | gRPC (public) API access (HAPI) |
| `50212` | TCP | Ingress/Egress | TLS-encrypted gRPC |
| `80` | TCP | Egress only | OS package repository connectivity |
| `443` | TCP | Egress only | Secure package & system update access |
| `123` | UDP | Ingress/Egress | Time sync via NTP pool |
| Port | Protocol | Direction | Description |
| ------- | -------- | -------------- | ----------------------------------------- |
| `50111` | TCP | Ingress/Egress | Gossip protocol |
| `50211` | TCP | Ingress/Egress | gRPC (public) API access (HAPI) |

| `40984` | TCP/UDP | Egress only | Block node streaming (gRPC) Publisher |
| `40982` | TCP/UDP | Egress only | Block node streaming (gRPC) Server Status |

> 📁 **Note:** Block node connections are outbound (egress) only; no inbound rule is required. Because block nodes are operated across multiple networks and the set of block nodes changes over time, allow egress on the block node ports (`40984`, `40982`) to any destination rather than to a fixed IP allowlist.

> 📁 **Further Note:** Block Nodes may configure other ports for the Publish or Server Status APIs. The exact ports for each block node will be available, once fully implemented, in the `RegisteredNode` entries in network state as defined in HIP-1137.
