HI, I'm very new with Firewalling and have read some HOWTOs ... not the whole IPTABLES or NAT Howto ... haven't much time at the moment. My Question is quiet simple : How do I setup a rule, that specify that the localhost ( linux-box ) cannot be pinged from outside ??? And ... how can I log all connection tried from outside ??? I've setup a "simple" isdn-router and a quiet simple firewall ... nearly everything is allowed, yet ... but this will change in some days/weeks :-) Mit freundlichen Grüßen Bruno Leonhardt CLP Domino R5 Systemadministrator ________________________________________________________________________________________________________ AnalyTek Systemhaus Hospitalstr. 2a D-65589 Hadamar Tel.: 06433/81403-15 Fax : 06433/81403-40
