Title: DHCP issue on VLAN
Post by: nikkon on March 01, 2022, 04:07:12 pm
Hi all,

I have a stupid problem.
I have 3 VLANS :
     Lan_Wifi tag 10 - 172.16.20.0/24
     Guest_Wifi tag 20 - 172.16.30.0/24
     Iot_wifi tag 30 - 172.16.40.0/24

Vlan 10 and 30 work perfectly. Every network has its own dhcp server.
Guest_Vlan which maps to a Wifi_Guest SSID, and has a DHCP server associated with it as well. The customers of this network are set not to have access internally, only internet access.
everytime I add a new customer, It gets the ip from the pool, the gw and dns. however is does 0 traffic.
If I add the device in the list of DHCP Static Mappings they start working as expected.
Once the client gets the ip from the dhcp server serving Wifi_Guest network, the client appears in the leases list as Offline


All other dhcp networks have mapping for every entry
Any clue why is this happening? I miss something for sure :(

thank you
