[Solved] My first Vlan: can you pls doublecheck the config

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello everybody,

I have installed OWRT on my router few days ago. Now I've tried my hand at the Vlan. You will find a scheme in the appendix. I share my internet with a friend from the apartment building. The new VLAN 10 is for his apartment. There is a switch and 2 PCs. I don't want it that he come into my network and vice versa.

with a scan with nmap in the 10.10.10.1/24 network, the devices in the 192.168.1.1/24 network are recognized except for the raspi.
but you can only access the router. that looks ok to me.

can you take another look at the config / network and the config / firewall? i haven't done this yet and i want to avoid a big mistake.

many thanks and greetings from thuringia

Everything looks fine to me.

The OG network does not need to be marked as a bridge, as you do not have a wifi network attached to it.
