What is the easiest way to play with modifying data in-transit within an ethernet bridge? For instance, say I have something like this: [BOX 1] <----> [ BOX 2 ] <----> [ BOX 3 ] And BOX 2 is a FreeBSD box with bridging enabled between two ethernet interfaces, how can I parse/modify the ethernet frames as they pass through? Eric
