SSL VPN lease pool to use DHCP

Hi,

We are planning to deploy SSL VPN using F5s, and the question that I would like to ask is Can the F5 uses DHCP scopes instead of a predefined leased IP Addresses Pool?

If the answer is No, and I define a pool with the same IP Addresses for the SSL VPN that for internal users: 10.10.10.0/24 Is there a chance the SSL VPN to uses the same IP Address as one given by DHCP to the internal user?

Thanks
