Thanks, I misunderstood the usage of /24. I thought in order to export to a whole subnet, I had to put the subnet address 192.168.0.0/24 while 192.168.0.20/24 would imply a single client within that subnet. I removed the prefix length entirely as CallMeAl suggested, so that’s sorted out.

There’s another issue remaining, see my reply to Al’s comment if you’d like.
