IPv6 IPsec servers won't be contacted

[Pentium4User]

Hello!

I want to connect to a IPSec/L2TP/PPP VPN on a Cisco router.
That works with IPv4, but not with IPv6. It doesn't even try to contact the router.

Apr 02 14:31:18 ubuntu-mate NetworkManager[1409]: <warn> [1712068278.7454] vpn[0x564ec09ee4c0,de43ed80-11c7-402c-90e4-e7a568b716dd,"886-IPv6"]: failed to connect: 'Message recipient disconnected from message bus without replying' Apr 02 14:31:44 ubuntu-mate NetworkManager[1409]: <info> [1712068304.9822] vpn[0x564ec09ee4c0,de43ed80-11c7-402c-90e4-e7a568b716dd,"886-IPv6"]: starting l2tp
kind regards

This VPN plugin is just a simple wrapper around xl2tpd, unfortunately xl2tpd doesn't support IPv6 yet:

• IPv6 support xelerance/xl2tpd#183

I should also add that NetworkManger-l2tp now also supports go-l2tp's kl2tpd for the L2TP daemon, it first tries finding kl2tpd and will fallback to xl2tpd if it can't find kl2tpd,

Although kl2tpd does support IPv6, I haven't modified Networkmanager-l2tp yet to support IPv6 with kl2tpd.
