I have 4 Deco X20's in a mesh, with the main node running in Wi-Fi Router mode (default).  The Deco app says I'm up-to-date on firmware.

The X20's have a pair of gig Ethernet ports out of them for local hardwire access, which is working well for the most part.

However, I am trying to RDP from a desktop computer wired into the main node to another desktop computer that is wired into a remote node.

Everything is enabled, RDP is allowed, I even have shares sharing from the remote computer, but nothing is getting through, not even ICMP.  It's like the nodes are only allowing traffic FROM clients, and now allowing traffic TO clients.

Basic network diagram:

[PC A]===Ethernet===[X20 Main] ))) Mesh Wi-Fi ((( [X20 Remote]===Ethernet===[PC B]

                                              ||

                                               \===[DSL Router]==={Internet}

The two PC's cannot see each other at all, but both can go out to the Internet fine.

What do I need to do in order for clients to connect to each other over the mesh?

Thanks,

Otto
