No, DCCP is much newer than most NAT hardware in operation.

When a client user agent is sending UDP, client-initiated TCP streams
such as HTTP or HTTPS persistent connections for all data from the
server including packet acknowledgment is likely to be the most
reliable.  Bandwidth from the server to the client is usually greater
than or equal to bandwidth from client to server.
