We use solarwinds to monitor our remote locations, we have it setup to ping the WAN IP to check if it's up. We can't seem to ping through our MG (which is in passthrough mode). Doing a packet capture at the MX we can see the request/reply but doing a packet capture on the MG we only see the request, not the reply.

Any ideas on what would cause this? The MX sees the public IP properly and uses that as it's uplink interface so it is running in passthrough, not sure what it could be
