Hello

I have fortigate firewall and i have 2 vlan. Let say vlan100 for NAS and vlan200 for cctv.

The cctv can connect to the nas only if cctv and nas located in same subnet, the cctv can't discover the nas if the nas located in different subnet. Can we make some forward broadcast to enable the cctv can discover nas even in different subnet?

    please post the whole output of the deny log.

     

    also, please provide more info about your setup, with specific interface/network allocation and the relevant policy and vip configuration.
