I have a machine running FreeBSD 9.0-CURRENT #3: Tue Sep 15 18:49:58 EDT 2009 amd64 It has this in the config file for the running kernel: options IPFIREWALL #firewall options IPFIREWALL_VERBOSE #enable logging to syslogd(8) options IPFIREWALL_VERBOSE_LIMIT=100 #limit verbosity options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default options IPFIREWALL_NAT #ipfw kernel nat support options LIBALIAS It (10.0.0.1) connects correctly to another machine (10.0.0.3); I know because .3 mounts one of .1's disks using Samba. With the ipfw rules appended below, I can't NAT, nor should I be able to. ("em0" faces the Internet; "em1" faces the other machine.) However: using these I still can't get through ipfw add 5000 nat 15 all from any to any ipfw nat 15 config log same_ports ip 10.0.0.0/8 Have I forgotten something? Or misunderstood something? If not ... how do I figure out what's wrong?
