what's the difference between a port TCP and UDP?
i am talking from a firewall concept,i want to know ,if i need to block a
port,when should i block TCP and when UDP and when both?
TCP is a connection oriented protocol, UDP is a connectionless protocol.
When to block what will depend on the service/program you're trying to allow
access. You'll have to look up the specifics for each one. If you're
confused on this issue, I recommend that you do some reading before you go
too much farther, something like "Building Internet Firewalls 2nd Edition"
by O'Reilly would probably be a good start.
