I setup a guest network as follow:

 

SSID: guest

subnet 192.168.100.0/24

 

I enabled "Guest Network" to isolate each wireless clients for security, a captive portal is running at the guest network gateway (192.168.100.1)

so I added an EAP ACL rule:

 

from SSID: guest

to IP Group 192.168.100.1/32

 

but it doesn't work, all clients connected can't reach 192.168.100.1 until I disable "Guest Network"

 

Any hints?

  @kkyyww Can you provide screenshot from that EAP ACL rule?

 

I'm using similar thing and it works fine.

I have policy "Permit" and protocol "UDP, TCP, ICMP".

I think I found an EAP ACL bug

 

I created several SSID for my guest network, 

 

guest

pantry

conference room

 

all actually shared the same VLAN (192.168.100.0/24) , just with different SSID name for different AP locations.

 

they all shared a same EAP ACL rule to permit 192.168.100.1 ( the VLAN subnet gateway, which run the captive portal as well )

 

If I create 3 EAP ACL rules and 1:1 map to the 3 different SSID, then the ACL rules work. All SSID can reach 192.168.100.1 

 

If I just create 1 EAP ACL rule and share it with more than 1 SSID, then the ACL rule stop working, all SSID cannot reach 192.168.100.1

 

Wish TP-Link can fix this bug

  @kkyyww 

nope. did not reproduce this. it works on three ssids: 1 vlan 1 ssid and 2 vlan 100 ssid(both enabled guest network)

allow

3 ssid > 192.168.100.1/32 ip group. 

ping works great.

could be your protocol issue?

controller version?

one more thing, my controller is at different VLAN and subnet from my guest wifi VLAN

 

controller IP is 192.168.99.1

guest wifi VLAN 192.168.100.0/24, gateway 192.168.100.1
