At first I wanted to make a statement that I am no expert, but I try to learn. I still prefer Luci GUI to console commands, so all my current config info is taken from there.
I've tried reading other topics with VLAN issues, but none seems to match my use case, most of them are about tagged VLANs, which I think I don't need right now (I still fully don't get an idea of tagged/untagged but from what I understand tagged ports are only needed when connecting another router to the ethernet port, not a single computer (which is my case)
Device: Netgear r6220 - MediaTek MT7621 ver:1 eco:3
OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.057.55219-13dd17f
My current configuration (interfaces):
- lan on 192.168.32.* - main network with WIFI access, everything close to defaults
- guest on 192.168.200.* - guest network with separate WIFI, without access to other clients
- iot on 192.168.100.* - untrusted devices with one more WIFI network, without access to internet and other clients. Only one device (a server) can have access to devices from this network
And this is working just great.
Now I wanted to have the same behavior as
iot interface but on wired connection. I connected another computer via LAN 3 port and went to Network -> Switch, added VLAN, set CPU to tagged, LAN 3 to untagged, and from VLAN 1 i set LAN 3 to off.
It looks like this: https://i.imgur.com/6nue6Mr.png
Then I went to interfaces, created "iotwired" interface, with Static Address of 192.168.101.1, without "bridge", of course I've selected VLAN eth0.3. Interface got DHCP server and new firewall zone "wirediot". Everything else was left default.
In the Firewall section in zones I set reject/accept/reject, just like I have in my
iot zone. No allow forward from/to zones seleced.
In Traffic Rules, I allow
wirediot to access Device on ports 67-68 (to allow DHCP to work) and I let access the server from
lan to allow forwards on all protocols to
But I can't ping or access services on devices connected to LAN 3 port (i've tried 3 devices). I've tried loosening the rules here and there and finally trying random switches and options but nothing helped.
Am I missing something?
Is it a bug?
Or maybe my Router is bad (I have other problems with it - randomly (I mean once a 3 days or a month) gets out of memory and stops working until manual reboot) and won't work with VLANs?
