Model: EAP225-Outdoor  
Hardware Version: V1
Firmware Version: 1.6.0 Build 20190722 Rel. 63596(4555)

Hi there,

I have Problems with the Vlan tag from the EAP225-Outdoor.

I run a EAP110-Outdoor with 3 multi SSIDs an 3 VLAN tags and a Zyxel GS1200-5 mgmt switch. Now i want use the EAP225 instead the EAP110, but all wlan ssid with vlan tag enable don't get to the network, only the default one.

 

EAP config by web interface (i use the same config for EAP110 and EAP225)

This config work fine with the EAP110

 

Static IP 192.168.188.254

Subnet 255.255.255.0

Gateway 192.168.188.254 (also tried 192.168.188.1)

All SSID broadcast enable

Security WPA-PSK

Time settings are up to date

SSID A Vlan 1

SSID B Vlan 10

SSID C Vlan 20

 

Zyxel config

Static IP 192.168.188.3

Subnet 255.255.255.0

Gateway 192.168.188.1

 

Port 1 EAP225 / Port 5 Router

Port 1-5 PVID 1 

Vlan 1 Port 1-5 untagged (default)

Vlan 10 Port 1 tagged + Port 5 untagged

Vlan 20 Port 1 tagged + Port 5 untagged

 

Router 

Static IP 192.168.188.1

Subnet 255.255.255.0

DHCP on

 

Have someone an idea or some troubleshootings ?

@Jay86, firmware version 1.6 for EAP225-Outdoor did fix a bug with VLAN leaks.

 

The correct way to use VLAN-mapped SSIDs is to terminate the VLAN in the router, not in the switch (except on L3-capable switches).

 

This means you have to create three subnets in your router, one for each SSID. Port 1 (the one the EAP is connected to) of your switch must be a tagged member in all three VLANs (1, 10, 20). If you don't use a Management VLAN for the EAP itself, it needs to be tagged, too.

 

From your description we can see that you use an asymmetric VLAN setup to share the same subnet among the three VLANs (e.g. traffic from clients in SSID C to the router uses tagged frames in VLAN 20, but traffic from the router to clients in SSID C uses untagged frames in VLAN 1). Asymmetric VLANs can't work with VLAN-mapped SSIDs. The router (or the L3 switch) must send traffic tagged with VLAN 20 in order to reach SSID C.

 

This is a correct setup for a VLAN-mapped Multi-SSID network (P3 is tagged member of all VLANs, P4 is untagged member of VLAN 200 only):

@R1D2 

Thanks for your reply,

The EAP225-Outdoor is up to date with:

1.7.0 Build 20200113 Rel. 35383(4555)

 

EDIT:

Ok sorry, 

I don´t now why but it works for a short time. Now the problem is still there

@Jay86, MAC filtering is unrelated to VLANs:

@R1D2 

My FritzBox don’t support subnetting. It still works on the EAP110-Outdoor with this configuration. (Expect 5Ghz)

I just use UPC*** 5GHz with VLan Tag at this moment i need the other WLan

EDIT: and i can connect to the web interface on the EAP225 any time without problems with Vlan Tag

 

 

 

 

Port 01 = EAP225 or EAP110 / Port 05 = Gateway/DHCP Server

@Jay86, good if it works for you.

 

Indeed, Fritzbox knows subnetting internally, but they hide it under »Guest Network« and »Network Settings« in the web UI. It allows for two subnets which have subnet IP 192.168.178.0 and subnet IP 192.168.179.0 by default (or a user defined network IP X.X.Y.0 and X.X.Z.0, where Z = Y+1). Thus, you can create two subnets at least. With a business-class switch you can assign them two different VLANs.

 

It's a pitty that FB can't do VLANs itself (AVM told me two years ago in a letter that VLANs are a »too sophisticated technique«). So I decided to use an UBNT EdgeRouter which runs an open (accessible) Linux system and to use the Fritzbox only as a cable modem, as a phone router and to heat my machine room in winter.

 

Guest network can be mapped to port 4, WLAN can be disabled:

 

 

 

Two subnet IPs can be chosen, where second subnet IP is always the value of first subnet's last network octet +1:

@R1D2 

 

The Network work fine befor, i dont buy a new switch to assign the IPs to the VLAN and i need 3 VLAN IDs not just 2. It is just a little private network for 3 parties living in a household and i want use the VLAN for privecy. Thank you for trying to help but that is not a solutions for me. If there is no other possibility, its better for me to use the EAP110 again an sell the EAP225. Sad about 5GHz WLan.

@Jay86, yes, the EAP110-Outdoor still has this VLAN bug. But that means you don't have privacy (no true VLAN isolation, package leaks). Just do a network scan to see what I mean. What's more, TP-Link might probably fix this bug in a future EAP110-Outdoor firmware, too.

 

It's not possible to use asymmetric VLANs unless you rely on a bug like this or unless you can assign a single SSID to more than one VLAN (and I know of no AP which lets you do that).
