1. Change your router from the Linux box to a L3 Switch, and create separate
VLANs for the internal/external users. Or...

2. Create a secondary address on your Linux box, acting as gateway for the
external users' address space.

sudo ip addr add dev eth0

This way, you'll have a true shared network, so you can serve 192.168.100.*
addresses on your dhcp server.
It may work, but I think it's a dirty solution.
