Linux Rule Based Routing

Given the following pre-condition:

Wifi dhcpd is setup to assign addresses in the range of: 169.254.0.225/27 to wireless clients (a 32 client address space);

AND your home router/gateway device runs Linux.

Then:

OP='add' To add route prohibit to Amazon destinations (from Wireless devices only), or
OP='del' to remove an existing route prohibit.

PHP Code:
/bin/ip rule $OP from 169.254.0.225/27 to 207.171.160.0/19 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 107.20.0.0/14 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 184.72.0.0/15 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 204.246.160.0/19 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 205.251.192.0/18 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 72.21.192.0/19 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 50.16.0.0/14 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 23.0.0.0/12 prohibit

/bin/ip rule $OP from 169.254.0.225/27 to 23.20.0.0/14 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 54.240.0.0/12 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 54.240.128.0/18 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 64.208.0.0/16 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 64.209.0.0/17 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 178.236.0.0/21 prohibit
/bin/ip rule $OP from 169.254.0.225/27 to 176.32.96.0/21 prohibit 
(Yes, I know that looks a lot like Cisco - but its Linux )

Which results in a pretty set of routing rules for the router's network stack:
PHP Code:
root@Microknoppix:~# ip rule

If you haven't seen that used before.
(Yes, Virginia, it handles IPv6 also.)

Note: Your non-wireless devices (ANY device with an IP outside of the source range above) can still access all Amazon services.
I.E: Manually download what you want and push over USB to the Kindle. (Such as books you want to buy - not the books Amazon wants to sell you.)
