    In part 1, I discuss access list fundamentals and I write a standard ACL and apply it to an outbound router interface using Packet Tracer. Click here for part 2: • Standard Access List (...

    Dear Sir, I took the CCNA exam on the 10/July scored 933/1000. Your lectures were extremely helpful especially the ones for topics such as ACL, NAT & Frame Relay which were difficult for me. If i didn't listen to your videos I would not have known anything about these topics. Thanks Sir.

  • @danscourses

    you use a 0.0.0.0 in the wildcard if you want to have the access list apply to only one host as opposed to a range of hosts like 0.0.0.255 which applies to 256 hosts (254 usable)

  • @danscourses
    @danscourses  11 ปีที่แล้ว

    intead of using a wildcard you can specify a host using the host keyword before the IP address like host 10.0.5.1 etc.

    Does this change at all when VLANs are involved? I'm running the configuration just like the video says but when I apply ip access-group 1 out to vlan1 my source that I'm trying to block which is on vlan3 subnet can still ping hosts on my vlan1 subnet.

    I still did not understand the outbound/inbound part. Coming out of the router, what does that mean? By how I understand, shouldn't it be inbound on the standard? Since it blocks forbidden connections?

  • @elmehdiilli4445
    @elmehdiilli4445 9 ปีที่แล้ว

    thanks for your video, my question is that if you deny as in your example the ping from the .2.101 to the .1.100 , should the ping works on the inverse side (from .1.100 to .2.101) or shouldn't ??

    • @sportalero9032
      @sportalero9032 6 ปีที่แล้ว

      Easy explanation: Tony represents 192.168.1.100. Chuck represents 192.168.2.101. They're in two separate rooms and Tony has his Access List Earbuds on full blast. Chuck yells out HEY!! but Tony can't hear him (Destination Unreachable). Tony yells out HEY!! and Chuck responds WHAT, A-HOLE but a-hole Tony never took out his earbuds so as far as he knows, Chuck didn't hear him (Destination Unreachable). Pings use ECHO REQUEST and ECHO REPLY. ACL prevented 1.100 from hearing 2.101's REQUEST. On the flip side, 1.100's REQUEST was received by 2.101 but ACL prevented the REPLY from reaching back.
