I have an access list that blocks the first part of a network outbound. This should block networks 1 thru 31. I am trying to replicate this line for an additional network but receive the message
ERROR: IP address,mask <172.17.0.0,255.240.0.0> doesn't pair
Here is the command that I am using :
access-list in-in line 6 extended deny ip any 172.17.0.0 255.240.0.0
Is there something that I am missing? The rule that I am tryig to match is
access-list in-in line 5 extended deny ip any 172.16.0.0 255.240.0.0
Ideas??
