Small Network Routing issues with Cisco ASA 5510

Edge R1 ===== ASA .1 --- 10.0.0.0 /24 .2 (Core R1) .2 ---Serial Link-- 10.253.253.0 /24 .1 (Router3) 10.2.1.0 /24

                           .1

                             |

                        10.1.1.0 /24

Here is my issue I can ping from 10.1.1.0 /24 to any device on 10.2.1.0

I can ping 10.0.0.2 from Any Device on 10.2.1.0

I can NOT ping any devices on 10.1.1.0 /24 from 10.2.1.0

I have set the security metrics the same and packet-tracer isnt giving me any warnings.

I am new to this realm, any help would be greate appreciated.I have enabled same-security-traffic permit inter-interface and thought that would do it.

Hi Jason,

Some observations:

On the ASA there's an ACL enabled on the MOC interface "access-group MOC_access_in in interface MOC" but it sees that ACL is not defined. Without an ACL allowing traffic that would be dropped.

Also it looks like there is no NAT defined between MOC and Inside - even if the traffic should not be NATted you'd still have to configure that.

The Packet Tracer should show you what goes wrong if an ICMP packet arrives at the MOC interface destined for the inside - try it and check the output....

Hope it helps!
