Hi All, I thought, that everything is just OK with my ip6 settings under my SUSE 9.1, but very recently my firewall started to complain concerning "ip6table_mangle": Sep 21 21:47:32 khazad-dum kernel: ip6_tables: (C) 2000-2002 Netfilter core team Sep 21 21:47:32 khazad-dum kernel: ip_tables: (C) 2000-2002 Netfilter core team Sep 21 21:47:32 khazad-dum kernel: ip_conntrack version 2.1 (4091 buckets, 32728 max) - 300 bytes per conntrack Sep 21 21:47:32 khazad-dum kernel: ip6table_filter: Unknown parameter `ip6table_mangle' I did the changes written by SUSE, how to disable ip6 networking, so in etc/modprobe.conf stands now: alias net-pf-10 ipv6 install ipv6 /bin/true Additionally in my /etc/sysconfig/SuSEfirewall2 is: FW_IPv6="drop" FW_IPv6_REJECT_OUTGOING="yes" Could you please suggest me a way how to block ipv6 completely, but avoid the above mentioned error message in the same time?! Do I actually need ip6_tables to be loaded?! (The machine is a stand-alone PC sometimes with eth0 via ip4, and sometimes with ppp0 via single dial-up...) Thanks in advance, Peli
