UDP & TCP 1433 question

[JoanO]

I received the following question from my operations group.

"When accessing a SQL server through a firewall, do you know if both UDP 1433 and TCP 1433 need to be opened?"

I know that TCP 1433 needs to be opened but I hadn't heard of UDP (User Datagram Protocol) until just now. I would assume it also needs to be open but I couldn't find a definite answer any where. Can someone confirm this for me? Thanks!

Just open TCP port 1433 would enough.
