I have a problem with an ASA5505. Let's say I have LAN1 (10.0.0.0/24) and LAN2 (172.16.0.0/24).
Machines in the LAN1 have the ASA(10.0.0.1) as the Default Gateway and a second router(10.0.0.2) connect the LAN1 to the LAN2. On the ASA device I have, of course, a static route to the 10.0.0.2 for the LAN2 network.
When a session beging from LAN1 to LAN2 everything is fine. When a session begin from LAN2 to LAN1 the ASA blocks the traffic in response.. No access-lists are applied on the inside interface and the same-security-traffic permit intra-interface is present (also tried with and without nat-control). Does anybody know how to work out the problem?
Thanks 4 your help.
