Advanced WAN: Configuring IPv4 over IPv6

This section describes how to configure IPv4 over IPv6 settings after selecting WAN1 as the connection interface. The EnGenius Gateway supports tunneling technologies such as DS-Lite, MAP-E, and IPIP to enable IPv4 communication over IPv6-based ISP lines.

IPv4 over IPv6 in VNE-Based Networks

In certain broadband environments, such as those provided by Virtual Network Enablers (VNEs), IPv4 connectivity is delivered over IPv6 infrastructure using tunneling technologies like MAP-E and IPIP (IP-in-IP). One widely used implementation of this model is commonly known as **v6 Plus**, which has been adopted by multiple ISPs to support high-speed access while preserving legacy IPv4 services.

Key characteristics of VNE-based IPv4 over IPv6 deployments include:

• - IPv4 access via MAP-E or IPIP - Optional static IPv4 assignment (typically with IPIP) - Integration with DDNS and authentication mechanisms - Routing and tunnel management handled by the VNE infrastructure

1. Connection Type Selection

After selecting WAN1 under Configure > Gateway > Interfaces > WAN, choose a connection type:

• - IPv4 over IPv6 (DS-Lite) - IPv4 over IPv6 (MAP-E) - IPv4 over IPv6 (IPIP)

2. IPv4 over IPv6 (DS-Lite)

For DS-Lite, configure the following parameters:

3. IPv4 over IPv6 (MAP-E)

MAP-E is a stateless tunneling method and does not require manual configuration.

4. IPv4 over IPv6 (IPIP)

For IPIP-based deployments, select a VNE type: v6Plus or Xpass. Each has distinct parameter requirements.

VNE = v6Plus (JPIX)

VNE = Xpass

5. LAN-side IPv6 Addressing

Under Configure > Gateway > Interfaces > LAN > Addressing, enable IPv6 using one of the following options:

• - Disable - Auto (DHCPv6-PD) - Auto (IPv6 Relay)

6. Gateway Monitoring

Both IPv4 and IPv6 addresses will display in:

• - Manage > Gateway List - Manage > Gateway Detail
