    Hi Mohammed, Thanks for reaching out to Sophos Community.

    There can be multiple things. If the network behind sonicwall is different than the network that the firewall is configured with, Then you'll need to add reverse routes to reach the network behind Sonicwall.

    If the routes are added or Sonicwall is configured as a transparent device, then check the NAT rule that is getting matched and see if the "Translated source (SNAT)" is kept as Original or MASQ. It should be MASQ for WAN traffic.
