FP has routed sub-interfaces as shown in diagram. HostA is able to ping HostB, and vice-versa. FP Vlan20 responds to ping request from HostA. FP Vlan30 responds to ping request from HostB. All works with the following exception, FP Vlan30 does not respond to ping request from HostA; and FP Vlan20 does not respond to ping request from HostB. (no nat; basic ACL allow). So 2-questions,
Is this normal for FTD?
And is it possible to configure FP 1/3 interface as an L3 virtual bridge on a switchport or trunk and associating the 1/3 Interface with the 1/2 Interface, then connecting the1/3 Interface to an access port on SwitchA vlan1; to allow tagged and untagged traffic to flow thru FP 1/3 Interface to SwitchA?
