Hello list! I want to begin to use iptables but I don't known how should I configure the Kernel. I installed SuSE 7.2 (Kernel 2.4.4) and I make following change in the Kernel: cd /usr/src/linux make xconfig option: Networking options/Network packet filtering (replace ipchains) set to Y make dep make clean make bzImage make bzlilo Then I booted the computer and use the new Kernel but some thing is wrong: root@linux:/var/log > iptables -L -v -n iptables v1.2.1a: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. root@linux:/var/log > iptables -F iptables v1.2.1a: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. where´s there the error??? Thx a lot! Herbert
