X2 port on a TZ400

MIS_ShopperWorld

I'm experiencing a strange hardware error. Last, week I was using the X2 port on the TZ400 and it was transmitting data from our internal network out to the net and VPN's were working. This week, the X2 port isn't working when we plugged in any external internet sources and the VPN's are no longer working. When, we move the cable to the X1 port then all communication and VPN's are working. No, changes were made on the TZ400, is there any diagnostic tests or log setting I can use to troubleshoot this?

Hi @MIS_SHOPPERWORLD,

Thank you for visiting SonicWall Community.

Do you see light status on the X2 port with a physical link on it? The below KB article steps should help you to if the physical port functions.

Hi @MIS_ShopperWorld

If your X2 port is responding / active, Check your Firewall Failover & LB configuration and make sure the X2 port is added in the Default LB Group.
