I would say probably not. SSL based vpn is pretty common, and that's always done over TCP. Cisco does support DTLS, and ipsec happens below TCP, so it just depends on your provider.

An SSL based VPN can be done within a UDP wrapper. The outer layer can't be encrypted or the connection wouldn't work. It's the payload that carries your (TCP/UDP) traffic out at the other end of your VPN.

OpenVPN is an SSL based VPN that can do either UDP or TCP, but defaults to UDP.
