I have a basic question, although a little tricky for me to understand. I was configuring some ACLs on a router, here is the thing I was trying to block TFTP traffic but by mistake I block TCP 69 port instead of UDP 69, both configuration successfully blocks TFTP. But here is the question, how come that blocking TCP:69 also blocks TFTP as TFTP works on UDP:69?
Thanks in advance. : ).
