An SPI (Stateful Packet Inspection) firewall will inspect the TCP SYN segment to determine if it is part of an established connection or a new connection request. If it is a new request, the firewall will check its rules to see if the source IP and port are allowed to initiate a connection to the destination IP and port. If allowed, the firewall will create a new entry in its state table to track the connection and forward the SYN packet to the intended destination.

It matters not if you have a UDP listener on the port. Telnet will not be able to establish a connection to a UDP port.
