Can't ping or browse devices connected to XG 125 firewall through unmanaged switch

Hi Paul Gonzaga: If your PING or access to the Printer is within the same network then the request will not come to a gateway device ( i.e. firewall in our case). However if the Printer and desktop are part of 2 different interfaces of XG and both those interface's zone are set to LAN then you may configure LAN to LAN rule to give it a try and confirm the status. (if a zone is different for those 2 respective interfaces then create a cross-zone rule if applicable else no action needed).

Hi Vishal_R, Thanks for your quick response.

I connected the unmanaged switch to port 4 of the firewall, and connected the printers (and desktops) on the switch. My assumption is that the XG firewall (router) is responsible for routing traffic regardless of whether the devices are directly connected to it or through the switch. 

I hoped that from one desktop, I can be able to browse the printers and also ping any other devices.

Am I missing a point?

Thanks

Hi Paul Gonzaga The source host wants to send a packet to another host on the same network. So in your case, it will use ARP to find another host’s physical address and traffic will be managed by switch ARP table or CAM table.

Please refer to this ARP-related blog for more references.
