# # For a network server, which has two interfaces, 128.1.40.1 (le0) and # 128.1.2.1 (le1), we want to block all IP spoofing attacks. le1 is # connected to the majority of the network, whilst le0 is connected to a # leaf subnet. We're not concerned about filtering individual services. # pass in quick on le0 from 128.1.40.0/24 to any block in quick log on le0 from any to any block in quick log on le1 from 128.1.40.0/24 to any pass in quick on le1 from any to any
