Nope, no harm.

The difference is that UDP is a connectionless protocol... so just pumps data down the line and expects the recipient to deal with it, any bad bits and it doesn't care.

TCP established a connection first, then checks each packet is valid, and requests a resend if a bad packet is found.

Best practice for firewalls is least access, but it won't do any damage....
