comment Interface ip address discrepancy
Aha! After asking the question, I realized that it had to be something to do with ARP and MAC address binding, but I knew nothing about host-model versus interface-model networking! Indeed, what I was trying to do may not be possible using linux ipv4. Thank you!

A nameserver was not being contacted. That was the really weird thing to me. The problem is now solved. Thanks!

comment Special setup for a linux server to route to itself
Beautiful! I had no idea it would be that easy! To enable two dummy interfaces I had to use the command modprobe dummy numdummies=2, and to make that persistent, the line option dummy numdummies=2 needed to be added to /etc/modprobe.d/local.conf (debian/ubuntu). Works perfectly!
