    To apply acl you type access-class, I’ve been typing access-group instead

    So does the VTY line encompass the entire terminal. Since you use inbound without specifying an interface but you also put the deny lines I'm guessing that means that a VTY line is kind of like 1 giant interface for all connections inbound or outbound of the router?

      Hey, great question. In the video I did an ACL entry permitting the entire NOC subnet of 10.140.1.0/24 to any using SSH. It was sequence number of 10. What you need to do is create an additional ACL entry denying the "other PC in NOC subnet for SSH" They key here is to use a lower sequence number than 20 so it gets hit before the entry permitting the entire subnet.
      For example if the PC you want to deny is 10.140.1.3 and you want to allow everything else in the 10.140.1.0/24 subnet to be able to SSH to the router:
      Extended IP access list SSH-ACCESS
      5 deny tcp host 10.140.1.3 any eq 22
      10 permit tcp 10.140.1.0 0.0.0.255 any eq 22
      20 deny tcp any any log
      Hope that helps and thanks for watching !

    Great video man. I have a question, how long did it take you from basic Network+ knowledge to being on the level of a CCIE? How many years roughly?
