My CPE forces me to use addresses from its LAN address range (192.168.1.0/24 and 2001:db8::/64) in my room and my PC prevents me to bridge wireless and wired networks. In 2006 IETF published `RFC 4389 `. Scenario 1 (section `1.1 `) describes exactly my situation! So there are some people who have thought about this and created NDP proxies. Basically my PC tells that the printer and the NetDisk are itself on the CPE LAN, and tells things in my room that it owns the IP addresses of the CPE, PC1 and PC2. Linux kernel of NDP proxies implementation was not really useful before 2012 because there were no way to list configured NDP proxies. Recent kernel (version >=3.3) implements what was needed for “ip neigh show proxy” command to work. With that, it’s quite easy to write a program which listens to NDP messages other the network and configures automatically the proxies. Several projects exist to do that but none take into account routing issues. Nevertheless most of these projects use two different address spaces at the two sides of the routers. Here I need to have the same prefix (2001:db8::/64) everywhere. So on my PC, both wired and wireless interface use in 2001:db8::/64 and I need to add specific routes to the addresses of my printer and my NetDisk or this to work. Therefore routes are automatically added when a new neighbor appears on the network. The software I’ve created is written in Python 2 and uses Scapy to sniff and send packets over the network. It makes call to the `ip` command to set up neighbor proxies and routes and maintains an internal state of the whole home network. That’s not scalable to big homes (or castles) but in such cases, routing several network prefixes is far more efficient.
