First of all, the output of the raw 'iptables -L' command is almost useless. You should use 'iptables -L -nv' or 'shorewall show'. As to why the rules are there, I suspect that you have another iptables configuration tool on that system and that it is started after Shorewall does when Shorewall is configured to run in level S. -Tom -- Tom Eastep \ When I die, I want to go like my Grandfather who Shoreline, \ died peacefully in his sleep.
