5506-x communicate between interfaces

simoneal — Fri, 21 Feb 2020 16:53:11 GMT

Hi everybody, on my 5506-x I have 3 interfaces, outside, inside and inside2. With this configuration I cannot communicate beteen 2 interfaces meanwhile on outside works. I add also same−security−traffic permit intra−interface option and now I can ping between but any other service dont works. Can someone help me please? Thanks

If the configuration have same-security-traffic permit inter-interface configured
and have 2 interfaces with same security-level value and you have "access-list" configured on both interfaces
then the ACLs will handle the decision of what traffic is allowed and what is not.

On quick look i do not see in your case i do not see any ACL,
