We know access-list 12 permit 22.214.171.124 255.255.255.0
is invalid, because the wildcard is wrong.
My problem is that the router did not give you any error message when type it in the router, instead it changed to access-list 12 permit 0.0.0.255 255.255.255.0 and added in the router. this cause a lot of problem because some of the network address is passed the filter.
Is it the bug in Cisco IOS?
