Theoretical question: a box has two interfaces, 172.16.100.1 and 172.16.200.1. I want each interface to ARP REPLY to ARP who has requests for all addresses in their /24 space. Would this accomplish that? -A FORWARD -j ACCEPT -d 172.16.100.0/24 --destination-mac 66:ec:27:90:78:00 -A FORWARD -j ACCEPT -d 172.16.200.0/24 --destination-mac 36:07:04:99:cd:09 If that's not any would somebody show me the correct rule? Thanks for any help, Mike Wright
