Address pool for Point-To-Site VPN

Hi guys, 

I have address space 172.30.0.0/16 with one VNet subnet 172.30.0.0/24 and Gateway subnet 172.30.1.0/24.

When I configure address pool 172.30.2.0/24 for Point-To-Site VPN I get an error that this range is overlapping with 172.30.0.0/16.

Should address pool for Point-To-Site VPN be outside of address space 172.30.0.0/24?

Regards
