You cant use 192.168.100.1 gw for 192.168.101/24 network the gw should
be an IP address inside the network.
You should define multiple IP addresses to your gw interface, lets say
192.168.100.1 mask 255.255.255.0
192.168.101.1 mask 255.255.255.0
192.168.102.1 mask 255.255.255.0
Then define these networks in your dhcp server separately so that if a
user gets ip from 192.168.101.0/24 network the gw will be set to
192.168.101.1.
You can also increase the number of IP addresses in your
192.168.100.0/24 network by decreasing the mask by using mask
255.255.252.0 then tell your dhcp server to give IP's in between
192.168.100.2-192.168.110.103.254
But I still suggest you to use PPPoE instead of this :) A lot less
trouble and supported in FreeBSD ppp implementation with radius support.
Plus by using something like mikrotik routeros you can limit the
bandwidth at the same time from radius server.
