Squidguard: Block all traffic for single IP with group ACL

[Banane]

Hi everybody,

I'd like to block all traffic for a single IP without a simple firewall rule, cause a redirect message shall show up.

When I use a group acl in squidguard for this client and set it to 'default : deny' the message from the common acl is shown, when a site is blocked.

When i use any other category than the default one in the group acl, the message defined within this acl is shown correctly.

Any ideas how to solve this ?
For example, how can a manual category matching 'all traffic' be defined ?

Kind Regards,
Paul
