Cross VLAN Traffic Problem

Unanswered Question

I have a switch which is layer 2, it is having IP address. The firewall interfaces connect it but in different VLANS. When I try to ping the switch with its IP address then Reply is going to the outside interface, but does not come back; I have checked the syslog server and found that the reply comes back on to the other interface of firewall. It is quite confusing as per the basic functionality. I have checked the config on the ASA but did not find something specific. Can any one of u suggest something. As per my understanding the data of one VLAN is going to the other VLAN. All suggesstions are appriciated.


Best Regards

Are you sure reply comes back to the other interface. Check if the inter-VLAN routing is enabled between VLANs with the help of a router for the communications to happen properly.
