We use it as a firewall, as a network traffic balancer, as a traffic director, and to balance the load to the 6 front end servers we have delivering a combined +50 million page views a month. IT has a rather cool feature called 'one-connect' where it makes a semi-permanent connection to your apache servers and pipes all traffic through that connection. This reduces significantly the overhead of opening and closing connections between the LB and the apache server. We currently have ours set to refresh itself every 1000 connections, but that is just caution and a slight case of paranoia in our part. The two units that make up the bigIP's solution are fully identical and can be used as standalone units, but when joined together they hearbeat monitor each other and complete redundancy in master/standby mode. The web-based https interface is really easy to get around in, and syncing the boxes is very very simple. The only drawback is price, new units are expensive, we paid close to $40k for the pair, but I can see them on eBay right now for under $5k for a pair, and I'm sure you can dig around and find an older model for less.
