src: support for RFC2732 IPv6 address format with brackets
The statement:
dnat to 2001:838:35f:1:::80
is very confusing as it is not so easy to identify where address ends
and the port starts. This even harder to read with ranges.
So this patch adds squared brackets as RFC2732 to enclose the IPv6
address.
