Hi
I've tried to set up OpenWRT to categorize network packets tagged with VLAN
information and act as a DHCP server on those VLANs. Using a configuration
where one port of the router is designated for one VLAN is straight
forward, but when managed network devices send VLAN tagged packets to the
OpenWRT router I was unable to get this working. After several tries and
resets of the OpenWRT router I'm here begging for help. This is the network
configuration I'd like to set up:
Asus N-16 (OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-188-g87e9837 Release
(git-16.043.44305-e2f9172))
WAN-Port --> WAN uplink to internet
LAN1-Port --> cable to a network switch that further spreads the network
over the entire house; cables only; referred here as "clan" (cabled lan)
LAN2-Port --> cable to ubiquiti ac-pro which provides:
--> "SSID1_2G"
* does not tag packets with VLAN information;
* bridged to "clan" sharing the address range and having full
access to "clan";
* same as "SSID1_5G" except that it runs on the 2Ghz radio
--> "SSID1_5G"
* does not tag packets with VLAN information;
* bridged to "clan" sharing the address range and having full
access to "clan";
* same as "SSID1_2G" except that it runs on the 5Ghz radio
--> "SSID2_2G"
* tags packets with VLAN id X;
* guest wlan that provides another dhcp subnet and access
internet only (i.e. the wan uplink);
* this vlan must not have access to "clan"
* access to the devices in "clan" must go through public ip,
loopback on OpenWRT and is thus reusing the port forwardings
Would you kindly help me figure out what levers need to be pulled on
OpenWRT to properly handle those two VLANs? Can OpenWRT actually handle
VLAN tagged network packets?
Cheers,
Dominik
