Inter-VLAN routing with sdn switch only
In addition to the TL-SG2428P I use a software Omada controler. My Internet rouer is a Fritz-Box.
I want to set up something similar to this TP-Link video: https://www.youtube.com/watch?v=-mkU3rI9coE
* 1: infrastructure (controller, eap, switch, router)
* 10: marketing department
* 20: R&D department
each of these set up with an own ip-range.
Once this is set up in the video, it states that all vlans can communicate with each other and have internet access. But No routes or whatever were configured.
This does not work in my setup. I tried static routes and switch acl's. But nothing enables my vlans to talk to each other.
As I am lacking the router, I question myself: is this a router feature? And if so - does all routed traffic need to go through the router cable (video: Port 13 on the switch)?
Also: isn't that a huge security flaw, to enable inter-vlan communication by default?
