while troubleshooting, I noticed something that i think it is wrong or unusual.
On my router interface fast1 i have acl 100 inbound and acl 200 outbound; both acl's have permit icmp any any .
When I ping with 4 packets (ping ip -c 4) from inbound, acl 100 counts only one packet and acl 200, 4 packets. Also if I repeat ping the same IP acl 100 count nothing and acl 200 counts 4 packets again. Only if I ping another IP acl 100 will count another packet.
This is counfusing for me, I think acl 100 should count like acl 200 4 packets.
I have a router 1812.
