Doing route selection based in part on source addresses is a form of policy routing, which has started to receive increased amounts of attention. In this paper, the authors extend the previous work on ROLF (ROuting as the Firewall Layer) to achieve source prefix filtering. This permits easy definition of "Inside" and "Outside", even in MANET environment where there is no topological boundary. The authors present algorithms for route propagation and packet forwarding using ROFL; they measure its performance in a simulated environment with two different adhoc routing protocols.
