openwrt:allow wan ssh into your wrt
by default,openwrt do not allow ssh access from wan, here are two method to change that:
1.login into your wrt from a lan host.issue the following command:
iptables -F
the command "flush away" all the firewall rules,including the one that rejects ssh request from wan.
now you can try ssh from anywhere.
aware that the firewall deactivation leads to highly security risk.and after the wrt restarts ,all default firewall configuration comes back.you hava to "flush" the rules once again.

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

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
