How can Vlans communicate on the Cisco ASA 5545

Posted on 2014-12-02

I have deployed a Cisco ASA 5545 device and within it I have Vlans.  One of the requirements for the deployment is for some devices in the Vlans to be able to communicate with other nodes in separate Vlans.

What can I do within the ASA to enable Vlans to communicate with each other.

Assuming that you have no IP access-listes other than default and the interface has same security level you need to add:

same-security-traffic permit inter-interface

This should be enough to allow them to communicate as far as I remember. If not then you might have to configure an access-list on both interface that specify what trafic is allowed.
