BigIP VE Lab

I agree it doesn't make much sense for LTM. F5 hawks their equipment as a firewall replacement along with LTM and GTM, so I'm trying to learn that part of it. I implemented LTM and GTM at work along with a Cisco firewall for a fortune 500 so I'm plenty familiar with those and networking. I'm not trying to do LTM, GTM, or traffic management here though. I'm trying to learn the firewall side of the BigIP. I bought a VE lab license intending to replace my home ASA with the BigIP. My only option on the outside is DHCP as I don't have a static IP available to me without upgrading to a business class connection. The only other option I can think of is a small static network between my ASA and BigIP and do double NAT.
