Huh? Did you set ipv6.disable instead og ipv6.disable_ipv6? Those are very different, as documented in the module: bjorn@miraculix:~$ modinfo ipv6 name: ipv6 filename: (builtin) alias: net-pf-10 license: GPL file: net/ipv6/ipv6 description: IPv6 protocol stack for Linux author: Cast of dozens parm: disable:Disable IPv6 module such that it is non-functional (int) parm: disable_ipv6:Disable IPv6 on all interfaces (int) parm: autoconf:Enable IPv6 address autoconfiguration on all interfaces (int) Bjørn
