Load the ipv6 module with disable=1, which is why I added it :) >>From Documentation/networking/ipv6.txt: disable Specifies whether to load the IPv6 module, but disable all its functionality. This might be used when another module has a dependency on the IPv6 module being loaded, but no IPv6 addresses or operations are desired. The possible values and their effects are: 0 IPv6 is enabled. This is the default value. 1 IPv6 is disabled. No IPv6 addresses will be added to interfaces, and it will not be possible to open an IPv6 socket. A reboot is required to enable IPv6. -Brian
