Various Network Configuration Output

Motivation

Use a Raspberry Pi as a bridge into my home LAN. The pi is plugged into a switch, which is plugged into an airport express, which is plugged into a cable modem; Nothing fancy.

This isn't a tutorial. Just some example output from a working setup.

steps

off the top of my head, here's the order I would do it in:

  • make sure plain old device to device zerotier is working with my LAN/Router/Firewall/ISP

making the ubnt wifi awesome (uap ac lite) w/ openwrt
making the ubnt wifi awesome (uap ac lite) w/ lede (openwrt)
the reasons you would do this:
- you get 802.11r
- you get better roaming
- you get access to some new 5ghz channels
I AM NOT TO BE HELD RESPONSIBLE FOR ANYTHING IN HERE. DO AT YOUR OWN RISK. THANK YOU AND HAVE A LOVELY DAY.
** note that though we're using Lede, it's essentially openwrt minus the drama

OpenWRT configurations to run OpenVPN client | Private Internet Access - https://www.privateinternetaccess.com

This gist contains all the OpenWRT configuraion files needed to connect to Private Internet Access (PIA) VPN servers. The following files are included:

  • network: contains configuration to add a virtual network device (i.e. tun1366) and custom DNS servers
  • openvpn: OpenVPN configuration file to connect to PIA VPN servers
  • firewall: firewall configuration which passes all traffic through VPN and rejects any request when OpenVPN is down

NOTE: there are a number of other files required to be available under /etc/openvpn for this approach to work:

  • pia.auth: VPN credentials in two lines, first the username and the second the password
