Syntax in Suricata YAML re: port ranges

[eldog]

I'm attempting to edit the Suricata template at /usr/local/pkg/suricata/suricata_yaml_template.inc to add some port variables in the "port-groups:" section for use in custom rules.  Looking at the docs, it seems like I can't add a range of ports like in Snort (i.e. 0:500), but that I must enumerate each one?

Am I understanding this correctly?  Am I going about this the right way?  Snipped below,

# Holds the port group vars that would be passed in a Signature.
  port-groups:
    {$port_vars}
     Allowed: "[1,2,3,4]"
     NotAllowed: "[1:4]"

Found a discussion on the subject here,

For anyone happening upon this I gave up, because it looks unsupported,  and just lived without the alias.
