Requirements for Entering IPv6 Addresses

IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by colons. Any four-digit group of zeroes within an IPv6 address can be reduced to a single zero or altogether omitted.

The following errors invalidate an IPv6 address:

•More than eight groups of hexadecimal quartets

•More than four hexadecimal characters in a quartet

•More than two colons in a row

IPv6 Filtering

When you enable IPv6 and select any connection type other than IPv6 Pass Through, the modem router starts the stateful packet inspection (SPI) firewall function on the WAN interface. The modem router creates connection records and checks every inbound IPv6 packet. If the inbound packet is not destined to the modem router itself and the modem router does not expect to receive such a packet, or the packet is not in the connection record, the modem router blocks this packet. This function has two modes:

•Secured. In secured mode, the modem router inspects both TCP and UDP packets.

•Open. In open mode, the modem router inspects UDP packets only.

Auto Detect
