If you create many groups, the LAN IP address used by the Default group members is 192.168.1.1,
the LAN IP address of the second group member is 192.168.2.1, and the following groups follow
the same rule.
If the IPTV function is enabled, the modem router automatically creates one interface group
named IPTV. If it is deleted, the IPTV function is not available.
4.18 IP Tunnel
An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to
transport another network protocol by encapsulation of its packets.
The modem router provides two IP tunnels: IPv6inIPv4 and IPv4inIPv6.
4.18.1 IPv6inIPv4
IPv6inIPv4 is an internet transition mechanism for migrating from Internet Protocol version 4 (IPv4) to IPv6.
IPv6inIPv4 uses tunneling to encapsulate IPv6 traffic over explicitly-configured IPv4 links.
Choose Advanced > Advanced Setup > IP Tunnel > IPv6inIPv4 to enter the configuration page.
To configure the IPv6inIPv4 tunnel, perform the following procedure:
