I agree, the above isn't all that hard.

However, I'd argue that the above is in some sense wrong.
There's no need to put all ICMP traffic in the same basket; some
ICMP traffic is required for e.g. path MTU discovery to work.
So, instead I'd use

access-list 175 permit icmp any any echo-reply

But you all knew that already, right? ;-)
