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

Paul Gonzaga

Hi there,

I have no experience with Sophos firewalls. I recently purchased XG 125 for a small office. I have done the initial set up and the device is connected to the internet. I connected a level one switch (unmanaged) to the one of the LAN ports. Printers and desktops are connected to the switch. Devices can get DHCP IP but, I can't ping them from another device. 

I want to configure printers but the web page won't load when in enter the IP address of the printer in a browser.

Like I said, this is the first time I am working with Sophos, maybe i missed something during the initial set up? I maintained the default zones.

Any assistance is much appreciated.

    Hi : 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 , 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
