I'm pretty sure my setup is correct here. So they are two separate networks therefore a broadcast for one should not go the other. If on the other hand you netmask was 255.255.252.0 then 192.168.0.x thru 192.168.3.255 would be part of the same network and you'd expect a broadcast to propagate. At least this is how I understand how it works, and I could be wrong. > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-net" in the body of the message > -- Bill Vermillion - bv @ wjv . com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
