I'd like to simulate an LFN over LAN - my idea is to install testing software on 2 hosts, traffic between them would be routed by the 3rd one - a FreeBSD based router. To simulate long RTT the router would have to delay packet forwarding in at least one direction - does anyone know how to do it? Is it at all possible withou some changes in kernel source code?

Dummynet is great, but at Gigabit speeds it has issues with regard to preservation of packet inter-arrival spacing. That may or may not be a problem for what you are trying to simulate however.
