ip6tables rule being rejected.

Show all headers | View raw

Hi,

When I try to add the following rule:

# ip6tables -t nat -A POSTROUTING -s 2001::/64 -d ! 2001:1::/64 -j ACCEPT
Bad argument `2001:1::/64'
Try `ip6tables -h' or 'ip6tables --help' for more information.

It is rejected. (Ignore the fact that this rule doesn't make a huge
amount of sense, it's a very cut down instance of the rule that I'm
really trying to add)

Leaving off the exclusion:
# ip6tables -t nat -A POSTROUTING -s 2001::/64 -d 2001:1::/64 -j ACCEPT
#

And there is no problem

The manpage suggests that it should work:
d, --destination [!] address[/mask]
     Destination specification. See the description of the -s (source)
flag for a detailed description of the syntax. The flag --dst is an
alias for this option.


Am I doing something daft or should this work?
