Help! What firewall rule(s) do I need in order to ping backwards through my network??? (I know this is a poorly worded question) I am trying to discover the devices on my network.

When I installed the Dude to the remote PC (100.0.0.15) I can see all the devices on my network and I can ping from (100.0.0.15) to (192.168.88.22), great. But now I would like to discover all the devices on my network from the local PC (192.168.88.22) and I cannot ping from (192.168.88.22) to (100.0.0.15).

I only have one firewall rule on each router (srcNAT: Masquerade)

I know the default gateway is used to pass traffic down the network, but how do I pass it back up the network?

Any help would be appreciated.

Can you do an /ip firew nat expo and post that here?

Note that when a discovery is done, it is done from the Dude server.
