  • Setup VLAN on OpenWRT using hardware that has no switch ports

    The new versions of OpenWRT (18 and newer) have the ability to add vlan interfaces directly from LuCI (web gui). You can now skip the manual editing of the /etc/config/network file. Using 802.1q in OpenWRT is very difficult when working on a device that doesn’t have a built-in switch or the when the switch chipset […]

  • Flashing om1p with stock openwrt

    I have many open-mesh OM1P units laying around from failed wireless projects. Needless to say I’m not a big fan of open-mesh and have some other projects in mind for this hardware. It was a painful process but well worth it. Now I have nice little OpenWRT units for any hacking pleasure. I have made […]

  • OpenVPN on the OpenWRT

    This outlines a typical VPN implementation with server, clients and routing. Using Attitude Adjustment 12.09. Although, this should work on any new version of OpenWRT. Last tested on version 17. Start by ssh’ing into the router and installing packages. root@myWRT:~# opkg update root@myWRT:~# opkg install openvpn-openssl openvpn-easy-rsa Create a “openvpnconfig” directory under config and move […]

  • OpenWRT, Access Point only config. LAN and PUBLIC wireless on an existing subnet

    In this scenario we will be implementing a openWRT as a wireless access point only. One wireless essid will be LAN accessible and the other will be segregated from the LAN but able to access the WAN. The openWRT in this example will not be the gateway to the network. Another device is the gateway […]

  • OpenWRT setting up a public wireless access that is firewalled from the LAN

    In this post I will outline how to use zones to create public firewalled networks. A device that can bring up multiple interfaces per radio is very attractive here. One essid for private wireless and another for open public wireless. The Atheros ath9k chipsets are very well supported in this regard because they are free […]

  • Setup PPTP server using OpenWRT

    DON”T USE PPTP ITS INSECURE!!

The router is Backfire 10.03.1 at address This configuration will setup the PPtP VPN server and it should be pointed out that its not a […]

  • OpenWRT, firewall to block public wireless users from private lan behind wan

    The updated and more flexible way to do this is outlined here. It also requires updated hardware. The wrt54gl only supports openwrt v10 (backfire). I would like to add that despite the wrt54gl literally being ancient, its still a rock solid device today. Of course, only if openwrt is installed! A while ago Second Street […]
