I'm having a heck of a time enabling ping to the external (public IP) interface of a Sonicwall 2040. I know it's disabled by default, but I've tried creating WAN to WAN access rules, WAN to LAN access rules, and NAT Policies, but still cant get a ping response.
If I take the Sonicwall off and connect a laptop configured with my static IP to the WAN link I get ping response immediately.
We are configuring failover and getting ping working will help our testing greatly. Any help much appreciated.
