Hello,
I am looking at a design were I'd be running a layer 3 switch = Sophos XG = Edge Router. I've never ran a firewall in transparent so excuse my ignorance. If I was to connect the XG lan interface to an access port on my switch on the same VLAN, I'd imagine this would work without issue. However, what if the XG receives packets from other vlans from my layer 3 switch to my router. Would it simply passthru with all security features or drop the traffic? Would I need to trunk through the XG in this case and create sub interfaces for all my VLANs from the switch? Ideally I would hope the XG passes traffic to my router while scanning regardless of what Subnet is coming from the lan.
