 * Hi, is the new WAF module compatible with a multisite/network installation? Jetpack
   is activated network-wide and sites mostly use their own top-level domain. Does
   the option have to be activated on each individual site or does it behave similar
   to Protect?

 * Hi [@ravanh](https://wordpress.org/support/users/ravanh/) –
 * Unfortunately, the Jetpack WAF module isn’t compatible with multisite at this
   time.

 * I suspected as much… The thing is: the Firewall module appears at the top of 
   the Jetpack > Settings > Security tab and can be enabled on each subsite of a
   multisite/network. What will happen if one or more sub-site owners/admins will
   activate the module? Is it going to cause issues or will it just not do anything?

 * Hi Rolf. This hasn’t actually been tested, since it’s not officially supported
   on multisite.
 * Our developers are looking into it, and we’ll get back to you once we know more.

 * Hi [@drawmyface](https://wordpress.org/support/users/drawmyface/) thanks for 
   letting me know. In wait of testing results, I’ll disable the Firewall module
   on our multisite installs…

 * I heard back from the devs, and due to the way the plugin manages php files globally
   for the IP lists, when you save a list on a subsite, any lists from other subsites
   will be overwritten. For that reason, we don’t recommend using this feature on
   a multisite installation.

 * Ok, so that’s about the manual rules? What about the firewall option/functionality
   itself? I mean, without the “Enable manual rules” option activated?

 * Hi [@ravanh](https://wordpress.org/support/users/ravanh/) –
 * Our development team advises against using the WAF in any capacity on multisite
   since it isn’t supported at this time.

 * Ok, thanks for confirming [@lastsplash](https://wordpress.org/support/users/lastsplash/)
 * I’ll be using my own plugin [Module Control for Jetpack](https://wordpress.org/plugins/jetpack-module-control/)
   to disable the Firewall option on the network 😉

 * That sounds like a plan, and it’s also nice to hear that you have your own standalone
   plugin for managing Jetpack modules. 🙂
