First thank you very much for answering this and other my questions. Very
clear and helpfull.
I will try to ask different thing. What could you tell about UDP echos. What
are these for packets???
When I typed access-list 100 permit udp any any eq ? I saw that it has echo
packets but not echo-reply as ICMP. Or it has echo replys. What are this
packets generally used for??
