Dear all,

As Is
I am currently using a Omada set-up with a non-Omada Router.
VLANs are created on the switch as Layer 2 VLANs (as I udnerstood it).
I am going to implement the ER707-M2 router, final configuration is shown below.

Questions
When creating a "New LAN" what is the difference in the Purpose between "Interface" vs "VLAN"?
If I select interface does this change how inter VLAN traffic is routed? Is then everything going through the router, which could create bottlenecks?
As I understood it, state full ACLs are not possible with switch VLANs.

Any PROS/CONS for using one or the other?

THANKS!

Additional Info
Planned Setup shown below, current setup is nealy the same but without the omada router.
