How to create an Webfilter with AND and multiple OR

Hi all,

I want to make an webfilter for the following situation

Hostname = IPXY AND Message text like tunneltype="ssl-tunnel" AND ( message text like "tunnel-up" OR message text like "tunnel-down")

How Can I do this?

The above setting seemt not to be working. How can I have AND and OR mixed?

I cannot implement the () in the filter.

regards

Willem
