  Hello @AINDER,

  We would need to perform a packet capture for ARP on the firewall to see what might be going on.

  The only reason that I can think of is, if the traffic from VLAN 10 is not coming with the tag of VLAN ID 10 to the firewall. In that case, the firewall will drop the requests made.

  Could you please check the VLAN tagging on the switch?

  Thanks!

  Hi @AINDER,

  Hope you are safe and fine.

  Could you please follow the below suggestions? These would help you to isolate the issue.

  • Could you ping the VLAN interface IP of SonicWall from the switches and see if switches can ping?
  • Similarly, please verify pinging the switch IPs from the SonicWall appliance's GUI as shown below.

  

  • You can perform a traceroute to the firewall's interface IP from one of the computers on the VLAN behind switch using traceroute command "C:\Users>tracert 10.0.10.254".
  • Lastly, we can perform packet capture at both switch and firewall levels to pin point the root cause. On the switch you can capture packets on a specific interface(s) using tcpdump feature. In SonicWall to perform packet capture, please use below web-link for just reference.

  Have a better day!!!
