Close.

The first one denies a source of 142.220.1.0 -> 142.220.1.15 source port GT
1023 to ANY destination (any port)

The second one denies a source of 142.220.1.0 -> 142.220.1.15 (all ports) to
Designation with port gt 1023

The keyword of ANY applies to the subnets (source or destination), if you
leave out the GT or LT then it equals all ports.

Subject: Simple ACL query

Is

 deny tcp 142.220.1.0 0.0.0.15 gt 1023 any

the same as

 deny tcp 142.220.1.0 0.0.0.15 any gt 1023

I read the first one as being deny anything from the 0-15 range with a
SOURCE port of GT1023 to any DESTINATION IP address. I read the second one
as deny anything from the 0-15 range on ANY SOURCE port to any DESTINATION
IP address on DESTINATION ports GT1023

Please can we just confirm this small thing.

Many thx
