Hi Please could you advise...... ( fedora core 2) I'm trying to configure Arno's firwall, but despite all my efforts it seems that iptables is not updating to what is specified by Arno's firewall script.. When I /etc/init.d/iptables restart The script runs and indicates that is has updated iptables rulse, and all is well .... But when I run nmap on both my private and public ip's there is no change.. The other problem is that squid's port 3128 doesn't show up .. What would cause such probles .. -- Gregory Machin greg@xxxxxxxxxxxxxx gregory.machin@xxxxxxxxx www.linuxpro.co.za Web Hosting Solutions Scalable Linux Solutions www.iberry.info (support and admin) www.goeducation (support and admin) +27 72 524 8096
