I'd like to ask you a question about ACL.
The setup I'm trying to do is keep C away from D.
In D, using the Advanced acl , the source ip was set to C equipment ip, and the destination ip was set to D equipment ip and denied.
And I apply it inbound on two links in the D device.
After checking that the ping does not go from C device to D device, D has to go to C normally, so I also checked the ping in D and the ping did not go to C.
So I asked around, I looked for it, and I apply an icmp icmp-type echo-reply on acl.
I applied echo-reply, but this time, I couldn't ping even A or B.
Do you happen to know what the problem is?
here is my config
