I have clients multiple clients on the following networks:

192.168.89.0/24
192.168.90.0/24
192.168.91.0/24

I have two users:

test1
test2

I would like to grant test1 access to clients on 192.168.89.0/24 and 192.168.90.0/24 but not 192.168.91.0/24.
I would like to grant test2 access to clients on 192.168.91.0/24 but not 192.168.89.0/24 nor 192.168.90.0/24.

I've solved it with huntgroups with individual client IP's but I need to do it by subnet.

I thought the following would work but it didn't.

/etc/raddb/huntgroups
hunt1 NAS-IP-Address =~ /^192\.168\.(89|90|91)\..*$/

Can anyone provide some direction?

Thanks
