Yes, RouterOS does not support OVPN over UDP.  I don't know about any TCP
issues - perhaps there may be some typical MTU issues, but since routerOS
can override MSS on any kind of link, if there is ever any problems they
would not be insurmountable.

Yes, as far as I know, encryption is an integral part of the OVPN protocol.

Doesn't really matter though - routerOS can support multiple VPN servers
simultaneously, so we simply enable the whole gammit and allow the client
side to connect using whatever method is available.

One other thing - I discovered that routerOS also supports IP-over-IP
tunnels.  That's a surprise - it must be a relatively recent addition! 

Cheers,  Mike.
