   Interested in sharing a web connection with neighbor, and want to do it with some thought to security.. I think a description for the setup I may want would be " being on different subnets" ?
   
   
   is dis the proper arrangement to keep us well enough isolated that one person's malware shouldn't threaten the other? each router performing DHCP / NAT

   You're on the same network...good luck.
   
   But free internet. You should just sniff their packets.

   I keep a MAC ID whitelist. That way I just get the MAC ID of the device of the person who wants to share the network and add it to the list. No other devices get access, therefore security concerns are minimized and have specificity.

   Depends on the router. I'm pretty sure some will send packets only on the port connected to the destination machine, and others just bridge their Ethernet ports.
   
   Using an open source firmware or enterprise router might let you have more control over what's going on.

   It's not the router you should secure, it's the terminals connected to it.
