Tunnel Gateway Overview
A Tunnel Gateway is a tunnel termination function provided within the OCX private network.
This feature connects a private network built on OCX with your on-premises network via an IPIP tunnel (IPv4 over IPv6).
Tunnel Gateway Configuration Items
To establish a connection between the OCX private network and your on-premises network via an optical line, you must configure the following Tunnel Gateway resources, line lists, and static routes as needed. The connection is finalized by performing an "Attach" operation to a VC (Virtual Circuit).

| No | Configuration Item | Description |
|---|---|---|
| 1 | Tunnel Gateway (Resource) | Creates a tunnel endpoint on the OCX network that bridges the optical line and the OCX private network. |
| 2 | Connected Lines | A list of optical lines that connect the Tunnel Gateway to your on-premises network. |
| 3 | Static Route | Allows you to configure static routing for the created Tunnel Gateway. |
