Latest reply: Feb 6, 2018 14:36:35 2615 4 0 0 0
Hello, I've been looking for the reflective acl command, but yielded no result, does anyone know what it is?

Quick background on what I'm trying to do
I have 2 routers, both connected to each other.
each router is connected to a switch,
each switch has 4 PCs connected to it.
router 1 gateway:
router 2 gateway:

I'm trying to get PC1 ( to ping PC5 (
but disable PC5 from pinging PC1.
So far it has been two ways, 
either both can ping one another or neither can ping each other.

Command used:
on router 1:
acl 3001
rule 5 permit icmp source 0 destination 0
rule 25 deny icmp source any destination any
int g0/0/0
traffic-filter inbound acl 3001
