Hi
We have a problem with disconnecting of Wi-Fi on the guest network.
The error seems to have to do with DHCP and Bonjour.
Bonjour feature:
A printer connected to LAN interface belong to VLAN 50 with a static IP.
Guest on the bridged network want to print from the customers guest network.
Involved VLAN and configuration
- 10 Wi-Fi “xxxx Public” 10.59.0.0/25,
Wireless – Configuration - SSIDS
Bridge mode, VLAN tagging. ID 10.
Bonjoure forwarding = Service VLAN 50 Services Printers
DHCP: Lease time 1 day.
- 50 Printer-Bonjour 192.168.50.0/24. DHCP do not respond to DHCP request.
Event
When I check appliance event logs, I can see a lot “Source IP and or VLAN mismatch”.
Almost all the alarms involve clients connected to the Guest Wi-Fi VLAN 10.
The timing is every 30 minutes on different clients.
The user has already a IP address from Guest network 10.59.0.0.
Connection is loost and the alarm shows below.
The alarm shows “source client assigned vlan: 50”
Last illegal ip mapped vlan id: 10
Configuration of Bonjoure on Security & SD-WAN -> Configure -> Firewall ->Bonjoure forwarding
- Service VLAN: Print-Bonjour
- Client VLANs: VLAN10
- Service: Printers
The printer connected to switch port belonging to VLAN 50 and a static IP from the same network.
I turned off DHCP on VLAN 50 before to see if the problem could have anything to do with it.
No luck.
