FortiWiFi SSID and PBX connectivity issue

Hello everyone,

I have a FortiWiFi device where I’ve configured 3 SSIDs as follows:

• veone air: DHCP pool 192.168.10.10 – 192.168.10.254, operating in tunnel mode

• veone tech: DHCP pool 192.168.20.10 – 192.168.20.254, operating in tunnel mode

• veone voip: DHCP pool 192.168.30.10 – 192.168.30.254, operating in tunnel mode

I’m able to connect to these SSIDs from my computer and complete my tasks without any problems.

Today, I received a PBX server that needs to be connected to the FortiWiFi on the internal4 port. The server requires a static IP address 192.168.30.3/24, which belongs to the same subnet as the veone voip SSID’s DHCP pool. This setup should allow me to ping the PBX server from devices connected to the veone voip SSID.

However, even though the PBX server is physically connected to the FortiGate’s internal4 port and assigned the static IP address manually, I am unable to ping it from the SSID network.

Could someone please advise on how to configure the FortiWiFi or what changes I need to make to enable communication between the veone voip SSID and the PBX server on internal4?

Thanks in advance for your help!
