Hi Rene,
The lesson is really great. Thank you very much for it.
I configured the network discussed. But changed loopback of R2 with another network behind R2. The access list was configured in the “out” interface of R2 to prevent all traffic except the http traffic from loopback of R1 to reach the network which replaced the loopback of R2. As expected it filters the traffic from R1 and allows http traffic from loopback of R1. To my surprise the traffic generated in R2 irrespective of it being http or ping is not filtered by the access list eventhough it is configured in the “out” interface of R2. Wonder how this can be explained.
Thank you in advance.
Regards,
Abey
