OpenWISP2 Deploy VLAN & Interface/Wifi on a Linksys WRT3200ACM with OpenWRT

[Justin Afzal]

Dear Sir or Madam,

i want to deploy my virtual switch-settings and my interface-/wifi-settings on a Linksys WRT3200ACM with OpenWRT firmware. When I manually configure the VLAN-Settings & Interface-/Wifi-Seetings on the Linksys WRT3200ACM it works fine, but when I want to deploy it via OpenWISP2 it won't work. The Linksys WRT3200ACM should act like an AP. It should pass through the devices to our DCHP-Server. The DHCP-Server answers with an IP for the selected network.

This is the manual configuration:

network:

config interface 'loopback'
 option ifname 'lo'
 option proto 'static'
 option ipaddr '127.0.0.1'

}

I tried it with OpenWrt 18.06.2 r7676-cddd7b4c77 and OpenWrt SNAPSHOT r9992-86fd8cb435. The Deploy of the Interface-/Wifi-settings only works, when I setup the virtual switch manually. When I delpoy the VLAN-settings, I won't get an IP from our DHCP. I also can't deploy two Temlpates with Interface-/Wifi-settings. It will create the two interfaces, but the wifi settings disappear. Can someone help me?

Kind regards
