Assumes you will be routing through the BIG-IP, hence the Internal and External names comes in picture. BIG-IP may be configured in a one-arm mode, and then use SNAT. If you are using a routed mode configuration it would be more likely that you would want more than 2 VLANS, placing a VLAN and SelfIP on each network that will in-house servers, and a "transport VLAN" on the "External" side that will have the inbound routes for the VIPS, and the default route out.
