I'm trying to understand VLAN tagging and how it works...
I have :
- Turris Omnia as main router (Turris OS 5.3.4)
- Zyxel GS1910-24 as network core
- TP-Link RE450 v3 as access point (OpenWRT 21.02.1)
The Turris Omnia router is plugged on lan0 to Zyxel GS1910-24 switch on port 20.
br-lan contains lan0.100
br-iot contains lan0.200
br-guest_turris contains lan0.300
The following configuration currently works :
If I plug a laptop to Zyxel port 2-8 : It has LAN IP
If I plug a laptop to Zyxel port 9-16 : It has IOT IP
If I plug a laptop to Zyxel port 19 : It has GUEST_TURRIS IP
All with matching firewall rules...
My issue is with a TP-Link RE450 v3 access point flashed with OpenWRT.
I would like to create Wireless SSIDs with tagged VLANs, while TP-Link eth0 plugged on Zyxel
But currently no matter what I try, it fails...
and Wireless clients optains DHCP lease from lan0.100 turris router.
If I try to mess with TP-Link eth0 vlan like "eth0.100" in network configuration, it mess everything and I can't plug the TP-link on the Zyxel switch anymore or it make whole Turris network crash.
I must unplug the TP-link and reboot the Turris Omnia...
To be honest I don't know how to configure the Zyxel for this particular need too...
Any help would be greatly appreciated.
