Its quite simple. There are two ( in real is it one and a link) scripts in /etc/ppp called ip-up and ip-down. If the interface-ip of your pppX-device changes even if a new connection is up or a running connection comes down these scripts are running. Simply call the firewallscript in the right start/stop section of the ip-up/down-script Michael -----Ursprüngliche Nachricht----- Von: Jost Schoeler [mailto:charly123@web.de] Gesendet: Mittwoch, 27.

Its running a PersonalFirewall but after the starting the personal-firewall I modified the system with "ipchains-restore < /etc/ipchains-rules to update the rules, I want to use. That's working fine, but when my dynamic-IP-Provider have canceled the Connection (after 24 hours) , I must always restart my script. What can I do after an IP-Change on PPP to do that automatic? Can I put the script in the IP-Up-Script? Sorry, my english isn't very good ;) Bye, Jost Schöler -- To unsubscribe, e-mail: suse-security-unsubscribe@suse.com For additional commands, e-mail: suse-security-help@suse.com
