Is there any way that I can check ( periodically or all the time ) that the IP the packet is coming from really is the one that the thing you can do is to hardwire (i think there is an option in the 'arp' command, but you might want to make it work together with DHCP) your ARP table so you might be passing out traffic, but the pkts generated by your router will never get to the correct destination. But other than that, no, IPFW does not currently even know the MAC address and so cannot check. luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
