Gl-ar750 and using other port for vlan with guest network

Sometime some vlan configs can burn out the switch. Is this one of those configs?

  1. went into luci/network/switch and untagged middle port on web page=ethernet closests to usb port for vlan 1

  2. clicked add and created a new vlan 2 and set it for tagged- untagged-off.

  3. I then rebooted the router.

  4. then went into luci/network/interfaces/guest/physical and added in custom eth1.2 and reboot. seemed to work fine. but special changes make for postive temperary results.

a. is this bad for this device? thanks

would make for a nice feature enhancement

I also tested using wwan 5ghz and setting wan(eth0) to lan and created a tor interface br-tor and changed and associtated it to a wireless-ap with its own dhcp and created a vlan-3 and added it to tor interface physical eth1.3
changed
in /etc/init.d/tor I changed moded gli-mod to – lan_ip=$(uci get network.tor.ipaddr)
and in /etc/firewall.user I changed-- ifname=br-tor

final config is 3 ethernet ports and three wireless aps and 3 different concurrent networks local interenet, vpn on guest, tor

Yes extroot being used here

Could you upload your related config files, print installed package list and firmware version?

Not sure if I did another run-on question. or not. but to respond to the middle port please keep in mind. on the gl-ar750,
From /luci/network/switch/
cpu lan1 lan2
n/a middle rj45port rj45port closests
to usb A port

my config above as flollow

WANPORT - LAN2 - LAN1 -USB (physical view on router)

LAN - guest - tor

eth1.1 eth0 - eth1.2 - eth1.4
