ACL to deny telnet from any host on subnet

[Deanmikawa]

Hello, I need to configure an ACL to deny telnet from any host on subnet 135.79.40.0/24 to anything on other subnets.  

I think I want to do something like this:

access-list 150 deny tcp host 135.79.40.0 0.0.0.255 any eq telnet

But I am not getting any results.... How can I configure my ACL to deny telnet requests from hosts on that subnet?

Attatched is a map of the network I am currently working with.  The goal is to deny telnet attempts from host E into router b and c, switch a and b.


Thank you,
Dean

Hi @Deanmikawa

 How did you apply the Access-List ?  You have shown how did you create it and looks ok but you did not show where did you apply it.
