TP-Link Router Config

Update 2021-04-29: This may still work for you if you've got an old TP-Link router, but this is not maintained and doesn't work with newer models. If you've got a newer router, other projects like tpconf_bin_xml will likely work better for you.

TP-Link allows you to backup and restore your router's config file. For some reason, they decided to encrypt these backups so you cannot modify them. I think this is dumb. This script lets you decrypt and re-encrypt your config files so you can modify them as you see fit.

I use this to modify my reserved addresses list because editing them through the web interface is terribly slow and cumbersome.

1. Go to the router and download the config file from the "Backup & Restore" section of "System Tools".
2. Run ruby tp.rb config.bin
