Content Filtering

Everyone I need a bit of assistance here. I am trying to setup a content filter rule for my Zywall 5 which block an HTTPS site. I with the rules was able to block all sub-site with the inclusions of a the root domain on the Forbidden web site list. I have also put the name of the domain on the keyword blocking list. However when we try to go to a subsite »https://subsite.blockeddomain.com traffic is allowed to pass. Anyone have a suggestion here I have looked through all of the documentation and it seems like I have setup everything correctly but HTTPS traffic still passes while all HTTP traffic is blocked correctly.

Thanks,
Alan

You're out of luck. ZyWall's capability to filter HTTPS traffic is very limited (IP / port based only).
HTTPS is encrypted thus ZyWall can't open packets and see the URL.

There are content filters for HTTPS that utilize SSL proxy ...ZyWall is not one of them :( (big weakness IMHO!)

I you are using the ZyWALL for DNS proxying/caching you could create a static entry for that host name that points to 127.0.0.1.

I've not done this, but I think it should work.

Otherwise you could put it into the hosts file.
