WHY WE NEED TO ADD PORT NUMBER 1433 TO TCP/IP PROTOCOL INSTEAD OF UDP PROTOCOL

HELLO EVERYONE,

WHILE INSTALLING SQL SERVER I HAD ENCOUNTERED A WARNING MESSAGE REGARDING  WINDOWS FIREWALL. AFTER SOME RESEARCH , I GOT TO KNOW THE STEPS TO TROUBLE SHOOT. IT SAYS I NEED TO GO TO WINDOWS FIREWALL AND ADD THE PORT NUMBER 1433 IN INBOUND & OUTBOUND SECTION USING THE PROTOCOL- TCP/IP & 1434 TO INBOUND & OUTBOUND OPTION  SECTION USING THE PROTOCOL OPTION  - UDP.

I WANT TO KNOW CAN I ADD THE PORT NUMBER 1433 USING UDP PROTOCOL INSTEAD OF TCP/IP PROTOCOL IN FIREWALL SETTINGS ; IF NO THEN WHAT IS THE REASON?

AND WHY CANT WE HAVE USE ONE PROTOCOL : TCP OR UPD AND ADD THE PORT NUMBERS 1433 & 1434 FOR ACCESSING SERVER & SQL BROWSER SERVICES ?

PLEASE HELP.

THANKS , SAURAV GHOSH
