Ubuntu 20.04 LTS on vServer(OpenVZ) cant config tunnel

[dreinetworks]

I have a vServer running with Ubuntu 20.04.

used the config from the tunnelbroker website:

Code Select Expand

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
        address 2001:470:1f0a:xxx::2
        netmask 64
        endpoint 216.66.80.30
        local 178.2xx.2xx.2xx
        ttl 255
        gateway 2001:470:1f0a:xxx::1

after saving I tried to restart network interfaces with
service networking restart

and got this message:

Job for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xe" for details.

systemctl status networking.service says following:

Oct 16 01:12:24 vserver1 systemd[1]: Starting Raise network interfaces...
Oct 16 01:12:24 vserver1 ifup[922]: Waiting for DAD... Done

Oct 16 01:12:24 vserver1 systemd[1]: Failed to start Raise network interfaces.

any help how I can make it run? thanks

check if you have module "sit" loaded

(lsmod | grep -w sit)
