Defines with which method the CLAT prefix should be generated.
- SNMP ID:
- 2.2.63.6
- Console path:
- Setup > WAN > 464XLAT
- Possible values:
- DHCPv6-PD
- If the Internet provider uses DHCPv6 prefix delegation, e.g. for DSL or cable connections, the CLAT mode DHCPv6-PD must be used. The subnet ID can be used to control which subnet of the delegated prefix should be used for the CLAT prefix. The subnet ID can be configured as 0, 1 or FF, for example.
- WWAN
- If the Internet connection is a cellular connection (WWAN), the CLAT mode WWAN must be used. The CLAT prefix is formed from the /64 WAN prefix. The subnet ID must be 0 or empty. NAT must be enabled in the IPv4 routing table for the WAN connection.
- Static
- If the Internet provider uses a static prefix, the static /64 prefix for the CLAT prefix can be used in the Subnet ID field, e.g. 2001:db8:: (without the /64 specification). This mode can also be used if 464XLAT is to be used on a VPN connection or tunnel interface. In this case, the VPN interface must have a static IPv6 address configured.
- Default:
- WWAN
