[SOLVED] If the wildcard is written as a mask in the ACL configuration, it will be invalid.
I did a test because I forgot what caused the wildcard in the ACL to be written as a mask.
Tested on the pt simulator and wrote an ACL
Access-list 115 permit ip 192.168.1.0 255.255.255.0 any
Then sh comes out
Access-list 115 permit ip 0.0.0.0 255.255.255.0 any
Then add 115 to port in and then ping the port, nowhere.
Then write a note below
Access-list 115 permit ip any any
Then ping, pass.
Does this mean that when the wildcard is written as a mask, the configuration is considered incorrect and will fail.
Thus 115 actually has only one deny ip any any , so it does not work.
