That will only work if you want to permit from source addresses in the
192.168.2.1 and 192.168.3.1 netblocks. I think you want a -s 192.168.1.1/23

When I was first starting out in IT, I was transitioning from Comms
Engineering, where I was mentored by one of the guy who helped build the
PSTN telephone network in AU. The two things he hammered home to me where;
* Always check the lines you're working on, and then checking the
numbers again.
and
* Always know how to use a different set of tools, because your
preferred one may not be available when you need it the most.
