Feature request: Multiple network / transport protocols for the same tunnel

[NiQ1]

In many cases it makes sense to use multiple protocols for the same tunnel. For instance, offer both UDP and TCP because UDP is preferred but sometimes people would have to use TCP because of firewalls. Also it would make sense to allow connections using both IPv6 and IPv4.

Unfortunately OpenVPN currently does not support this, unless you create multiple instances, each with its own allocated subnet. It would be really nice if we could specify multiple protocols in the same configuration.

This is already work in progress and planned to hopefully land in openvpn-2.7 (next major release)
