I am swapping my pfSense with Sophos XG Home for lab testing. I am encountering an issue where the connection to my TrueNAS SCALE shows "invalid TCP state" in the firewall log. Ping works, but not HTTP/S and SMB. The firewall rule is set to All-ALL, with no policy is attached for testing.
Scenario 1:
The client is a physical device on Native VLAN 110.
When TrueNAS has one interface with VLAN 109, no issue.
When TrueNAS has one VLAN attached to the physical interface with VLAN110, no issue connects to both interfaces.
When TrueNAS has two VLANs attached, only one VLAN can be accessed, but not the physical interface or other VLAN.
Scenario 2:
The client is in ESXi on VLAN 111.
Unable to access any interface on TrueNAS.
In both scenarios, the client can ping to all interfaces on TrueNAS, but "invalid TCP state" denied all connections on the firewall.
