Something has messed up natd. If I don't have the punch_fw option in the /etc/natd.conf file it eventuially core dumps with a bus error. I think this started JUST BEFORE the KSE commit. /etc/natd.conf: ( note that this works. comment out the punch_fw option and it core dumps ) use_sockets yes same_ports yes unregistered_only yes interface rl0 punch_fw 5000:50 natd stuff in /etc/rc.conf: natd_enable="YES" natd_flags="-f /etc/natd.conf" natd_interface="rl0" # rl0-external ifc : fxp0-internal ifc ipfw list: ( this is the SIMPLE firewall type rules with the addition of rules 400 and 500 ) 00100 allow ip from any to any via lo0 00200 deny ip from any to 127.0.0.0/8 00300 deny ip from 127.0.0.0/8 to any 00400 allow tcp from any to any via fxp0 00500 allow udp from any to any via fxp0 00600 deny ip from 192.168.1.0/24 to any in via rl0 00700 deny ip from 168.150.177.152 to any in via fxp0 00800 deny ip from any to 10.0.0.0/8 via rl0 00900 deny ip from any to 172.16.0.0/12 via rl0 01000 deny ip from any to 192.168.0.0/16 via rl0 01100 deny ip from any to 0.0.0.0/8 via rl0 01200 deny ip from any to 169.254.0.0/16 via rl0 01300 deny ip from any to 192.0.2.0/24 via rl0 01400 deny ip from any to 224.0.0.0/4 via rl0 01500 deny ip from any to 240.0.0.0/4 via rl0 01600 divert 8668 ip from any to any via rl0 01700 deny ip from 10.0.0.0/8 to any via rl0 01800 deny ip from 172.16.0.0/12 to any via rl0 01900 deny ip from 192.168.0.0/16 to any via rl0 02000 deny ip from 0.0.0.0/8 to any via rl0 02100 deny ip from 169.254.0.0/16 to any via rl0 02200 deny ip from 192.0.2.0/24 to any via rl0 02300 deny ip from 224.0.0.0/4 to any via rl0 02400 deny ip from 240.0.0.0/4 to any via rl0 02500 allow tcp from any to any established 02600 allow ip from any to any frag 02700 allow tcp from any to 168.150.177.152 25 setup 02800 allow tcp from any to 168.150.177.152 53 setup 02900 allow udp from any to 168.150.177.152 53 03000 allow udp from 168.150.177.152 53 to any 03100 allow tcp from any to 168.150.177.152 80 setup 03200 deny log tcp from any to any in via rl0 setup 03300 allow tcp from any to any setup 03400 allow udp from 168.150.177.152 to any 53 keep-state 65535 deny ip from any to any gdb traceback: su-2.05# gdb -c natd.core /sbin/natd GNU gdb 5.2.0 (FreeBSD) 20020627 Copyright 2002 Free Software Foundation, Inc.
