Source IPv6
Address/Mask
Length
Set the source IPv6 address of the packet to be filtered.
• When specifying only 1 IPv6 address, set the prefix length to 128. For
example, when setting 2002:C0A8:1234:0123:4567:89ab:cdef:0123/
128, enter 2002:C0A8:1234:0123:4567:89ab:cdef:0123 into the IPv6
address field and 128 into the prefix length field.
• When specifying an IPv6 address range, usually set the prefix to a value
less than 64. For example, when setting 2002:C0A8:1234::/48, enter
2002:C0A8:1234:: into the IPv6 address field and 48 into the prefix
length field.
• If " " is entered in the IPv6 address field, all packets are filtered.
Note
When specifying an IPv6 address range, even if this product's IPv6
address is included in the range, this product will not be filtered. When
