Not 100% sure but this may mean that multihome has not been ported to IPv6 yet. Perhaps you can open a ticket at https://community.openvpn.net/openvpn (you have to register and login first). > With tcp6-server this works. Yes, because with TCP the source address selection is performed directly by the OS internally. Using TCP was indeed the suggested workaround before UDP multihoming was introduced in OpenVPN. -- D.
