I'm trying to use tcpdump to troubleshoot a problem with ipnat. It doesn't
see the ping packets, though. All interfaces reply to ping, but tcpdump
doesn't show any icmp traffic. I even tried "tcpdump -itu1 'icmp[0]=8 or
icmp[0]=0'" to specifically dump just ping packets, but tcpdump keeps
quiet. Could this be ipfilter specific?
