If it does NAT, then by definition it is a router. It may not be a very good or configurable one, but it has two interfaces and selectively routes packets from one to the other while changing them (NAT). > I had my devices working for a while (a few months) but had no occasion to do > anything like ssh between them.

Any of these three options are available to you: * You can turn off NAT on the EdgeRouter, connect it to the TMO thing, and go from there. * You can connect the TMO thing to the EdgeRouter on a LAN port instead of a WAN port, and avoid NAT that way. * You can buy a cheap ethernet switch ($20-40) and connect it to the TMO thing, then connect the other computers to the switch. > 2.
