I'm looking at monitoring some of my client's WAN connections from our main probe here at my office. While I do have a remote probe at their office, I was planning on running simple ping tests to their main firewall. A couple of these clients have Dual WAN Failover setup on Sonicwalls. However, when I setup the ping tests, the second test is always dropped by the Sonicwall as an IP spoof.
Any suggestions on how I can still monitor each connection without having it be detected as an IP spoof?
