Any easy technique to figure out in which direction to configure ACL on an interface. It is kinda confusing.

_______(IN)LAN Interface(OUT)----ROUTER-----(IN)WAN Interface(OUT)____________
Every interface has got in/out so if you want to control LAN traffic going outside - Outbound ACL -IN direction.
If you want to control WAN Traffic going Inside-- Inbund ACL --- OUT direction.
Though you can drop packet anywhere but always better to drop before in gets into router.
Hope this helps.
Thanks

Hi,
When you apply an ACL "in", the router examines all traffic it RECEIVES on the interface against the ACL.
When you apply an ACL "out" on an interface the router examines any traffic attempting to leave that interface against the ACL.
Please rate the helpfull posts.
