Say the two subnets are 193.4.5.x broadcast will be 193.4.5.255 130.111.7.x broadcast will be 131.111.7.255 Thus machines on subnet 130.111.7.x will ignore broadcasts on the other logical subnet and vice versa. What I want is the FreeBSD box to take broadcast packets in on one logical subnet and repeat them on the other so that all machines see the broadcast. Changing to two class C network addresses that are sequentially numbered is not an option :-( Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
