I’m doing a lab for school, part of the lab requires I setup 2 ACLs on a router I thought I had configured them correctly however, one of the routers(R1) cannot ping another(R3 fa0/0/) that it should be able to. I have looked in my textbook, googled it, and messaged my professor(3 days and no reply). Any help is much appreciated.
The instructions are as follows:
“Create 2 ACLs on R2 that allow all ip addresses within the 192.168.1.1/24 subnet and RIP update messages from R1”
Im also given the beginning of the acl statement and left to fill in the blank
“Access-list 20____”
Notes that may help:
R1-fa0/0 192.168.1.2
R1-fa0/1 10.251.1.1
R2-fa0/0 10.251.1.2
R2-fa0/1 10.251.2.2
R3-fa0/0 192.168.2.2
R3-fa0/1 10.251.2.1
My ACL configuration performed:
Ip access-list 20 permit 192.168.1.0
Ip access-list 20 permit 10.251.1.0
Access-list 20 permit any
Interface fa0/0
Ip access-group 20 in

It's hard to tell but the way you have it lay out your IP address maybe wrong on R3 or you don't have a route to and back from R3. Need some show commands and the running configuration. If you did this in packet tracer you can share it from Dropbox or Google drive.
