[Firehol-support] Mixed IPv4 and IPv6 variables

Hi Arthur

For some reason your message was filtered before it reached the list.
Most likely it was sent as HTML-only or something? Anyhow...

At the moment you can only pass both IPv4 and IPv6 to a single
command by using as e.g. src4 and src6 and two separate lists.

The special variables are specially expanded (when the name is
recognised), it's not a general mechanism.

Not out of the box. It starts to get very hard to define what
the behaviour should be if one half of the list is empty.

Obviously the config file is a bash script so it should be
possible for you to define a custom function that splits a single list
apart and then makes a call to a normal FireHOL rule.

Hope that helps
Phil
