Routing issue

[Florin Vlaicu]

I am running a server in a container that uses a macvlan interface to
have a static IP address in my local LAN. Then from my router I DNAT
to that IP address.
If I stop the container and then start it on another host (with the
exact same configuration) existing tunnels will fail, but new ones
will work.
If I just restart the container (or even reboot the host) the existing
tunnels will come back up.
Is there something I can change on the clients to not have to restart
the tunnel?

Thanks,
Florin
