Hi. I'm need create gre tunnel for ipv6. I do in command line: ip -6 tunnel add mode ip6gre remote 2001:db8:1::1 local 2001:db8:2::2 ip -6 addr add 2001:db8:3::1 dev ip6gre1 ip -6 route add 2001:db8:3::2 dev ip6gre1 ip -6 link set dev ip6gre1 multicast on ip -6 link set dev ip6gre1 up and this work! However then me write in /etc/conf.d/net: iptunnel_ip6gre1="mode ip6gre remote 2001:db8:1::1 local 2001:db8:2::2" config_ip6gre1="2001:db8:3::1 peer 2001:db8:3::2" and create /etc/init.d/net.ip6gre1 as a symlink on /etc/init.d/net.lo, and after do: /etc/init.d/net.ip6gre1 start i see: alex@host # /etc/init.d/net.ip6gre1 start * Caching service dependencies ... [ ok ] * Bringing up interface ip6gre1 * Caching network module dependencies need firewalld * Creating tunnel ip6gre1 ... Unknown tunnel mode "ip6gre" [ !! ] * ERROR: net.ip6gre1 failed to start I try change "iptunnel_ip6gre1" on "ip6tunnel_ip6gre1" or "iptunnel6_ip6gre1" but results was not good: alex@host # /etc/init.d/net.ip6gre1 start * Caching service dependencies ... [ ok ] * Bringing up interface ip6gre1 * ERROR: interface ip6gre1 does not exist * Ensure that you have loaded the correct kernel module for your hardware * ERROR: net.ip6gre1 failed to start I'm think what problem in file /lib/netifrc/net/iproute2.sh, in function: _tunnel() { ip tunnel "$@" } Most likely it is necessary, that if tunnel protocol is ipv6, this function has to look different, but i don't know how.

Please test netifrc-0.2.4. It seems the ip6gre tunnel mode was newer than the rest of the code; if you could run your 4 testcases again with it, that would be superb in debugging it. Reopen if it's still buggy after that.
