('cat <file> iptables-restore' will restore that table accordingly)
another useless use of cat
iptables-restore < file
Sorry, beginners idiocy, copying stuff from a tutorial he read.
Unfortunately I am working with a dynamically assigned IP that is passed to the iptables script called in /etc/ppp/ip-up by pppd.
Why do you care about your IP in the firewall rules? Use interface matching instead!
Although it is hardly imaginable that someone <tm> manages to spoof the interface match, I wanted my rules as tight as possible thus using interface _and_ DynIP ('$IPTABLES -A INPUT -p tcp -d $IP_INET -i $DEV_INET -m state --state NEW -j BLACKLIST')- it would naturally all be solved if I refrained from using variables and resorted to -i ppp0 instead.
But since I'm experimenting and learning, some non-pragmatical approaches may occur, especially since I want to keep the script as generic/cross-distro-usable as possible :-)
Thanks anyway
Martin
