To all, If I say:
block in quick on em0 from 83.0.0.0/8 to any That should block all protocols, right? I've got this rule enabled, but I received an ICMP packet from an address within this block. My rule structure is -------------------------------------- Pass in quick on <local interface> Pass in quick on <internal interface> Block in quick on <external interface> <offending addresses block> ... Pass in quick <valid traffic> ... My environment is -------------------------------------- OS: FreeBSD v. 4.10-RELEASE IPFILTER: v. 4.1.3 External Interface: em0 Any thoughts would be appreciated, Matthew Lee
