View source for OpenWRT on Asus WL-500gP: Installation Guide

''update note 8/9/2010: This guide is for the Asus WL-500g Premium version 1 which has the Broadcom 4704 (Broadcom 4318).  Asus rereleased the WL-500gP with a slower chip that is not yet supported.''

== Replace Firmware with Linux ==

<big>'''1.''' </big> Access Asus router via web browser from PC.  Programmed WAN IP address and network information.

<big>'''2.''' </big> Powered off the Asus router.

<big>'''3.''' </big> Downloaded openwrt-brcm-2.4-squashfs.trx and saved to my PC local disk.

<big>'''4.''' </big> Disabled all NIC's on the PC except for the one connected to the Asus.

<big>'''5.''' </big> Held in black "restore" button on back of router while powering it on.  Waiting until power light (orange broken circle with line in top) stopped flashing.

<big>'''6.''' </big> Ran ASUS "Firmware Restoration" utility.  Selected the file "openwrt-brcm-2.4-squashfs.trx" and submit.  Waiting until status bar went across screen, then watched router reboot.  Waiting another five minutes for good measure.

::instructions on using firmware restoration:  
::*Disable all but one network interfaces on your PC. This is nessesary because the firmware restoration tool is not very intelligent in finding the correct interface to use for communicating with the router.
::*Configure Windows TCP/IP networking to have static IP address 192.168.1.10 as shown in this image.
::*Disconnect the power cable.
::*Press the reset button on the back of the router.
::*Keep pressing the reset button while inserting the power cable again.
::*Keep pressing the reset button until the power LED starts flashing every second.
::*Start the firmware restoration tool on your PC (You can find this tool on the CD or download it from the Asus website).
::*This tool should find the Asus router -> select it.
::*Select the correct firmware file you want to upload. Double check again if it's the correct one!
::*Press upload.

<big>'''7.''' </big> Using a web browser on the PC accessed the router on 192.168.1.1 and set a root password.

<big>'''8.''' </big> Using SSH accessed the router as 'root' and the new password and checked everything out.

== Network Configuration ==

My desire is to have 3 interfaces, one WAN, one LAN, and one WiFi. (screened subnet architecture)

Here are some notes on vlans with OpenWRT:
:*hwname is always eth0, the switch itself.
:*always include port 5 because it is how the traffic is seen by the CPU (internal tagged port)

configuration concept:
 Port 0: WAN:: vlan1 - connect to router, public IP address
 Port 1: LAN1: vlan0 - connect to network switch, private LAN IP address
 port 2: LAN2: vlan1
 port 3: LAN3: vlan2
 port 4: LAN4: vlan2
 Wifi :::::::: vlan2

* It's a good idea when choosing a vlan layout to keep port 1 in vlan0. At least the WRT54GS v1.0 will not accept new firmware via TFTP if port 1 is in another VLAN.

<big>'''1.''' </big> Configure interfaces and vlans

 nvram set vlan0hwname=et0
 nvram set vlan0ports="1 5*"
 
 nvram set vlan1hwname=et0
 nvram set vlan1ports="0 2 5*"
 
 nvram set vlan2hwname=et0
 nvram set vlan2ports="3 4 5*"
 
 nvram set wan_ifname=vlan1
 nvram set wan_ifnames=vlan1
 nvram set wan_ipaddr=PUBLIC.IP.ADDRESS
 nvram set wan_netmask=255.255.255.248
 nvram set wan_proto=static

 nvram set lan_ifname=br0
 nvram set lan_ifnames="vlan0"
 nvram set lan_ipaddr=192.168.XX.1
 nvram set lan_netmask=255.255.255.0
 nvram set lan_proto=static
 
 nvram set dmz_ifname=br1
 nvram set dmz_ifnames="vlan2 eth2"
 nvram set dmz_proto=static
 nvram set dmz_ipaddr=192.168.XY.1
 nvram set dmz_netmask=255.255.255.0
 
 nvram set ifup_interfaces="lan wan wifi dmz"
 
 echo `nvram get vlan0ports` > /proc/switch/eth0/vlan/0/ports
 echo `nvram get vlan1ports` > /proc/switch/eth0/vlan/1/ports
 echo `nvram get vlan2ports` > /proc/switch/eth0/vlan/2/ports

I'm going to write this to nvram.  

 nvram commit

Note that lan, wan, and wifi are reserved names meaningful to the firmware.

Now I'm switching the wire from port 1 to 4 and changing the PC IP to 192.168.XY.10.

SSH into the router 192.168.XY.1

 nvram set lan_ipaddr=192.168.XX.1
 nvram set lan_dns=DNS.SERVER.YOU.CHOOSE
 nvram set wan_ipaddr=PUBLIC.IP.ADDRESS

 /etc/init.d/S40network restart

I'm going to write this to nvram.

These settings should be retained after a reboot.  I have noticed that sometimes after a reboot the USB device does not show up.  

Installing and using IPKG packages in mount point other than root
*(I did not complete this procedure)

 echo dest usb /mnt/disc0_1 >> /etc/ipkg.conf

Booting from the USB drive, with failover to the Flash

 umount /dev/scsi/host0/bus0/target0/lun0/part1
 fdisk /dev/scsi/host0/bus0/target0/lun0/part1

*Press 'd' to delete 1, 2, 3, and 4
*Press 'n' for new
*Press 'w' for write

 ipkg install http://downloads.openwrt.org/backports/rc5/e2fsprogs_1.38-1_mipsel.ipk

 mkdir /tmp/root
 mount -o bind /rom /tmp/root
 mount -o bind / /tmp/root
 cp /tmp/root/* /mnt -a
 umount /tmp/root
 umount /mnt

 rm /sbin/init

And replace it with this script: 

 <nowiki>#!/bin/sh</nowiki>
 <nowiki># change this to your boot partition</nowiki>
 <nowiki>boot_dev="/dev/scsi/host0/bus0/target0/lun0/part1"</nowiki>

 <nowiki>for module in usbcore ehci-hcd scsi_mod sd_mod usb-storage jbd ext3; do {</nowiki>
 <nowiki>  insmod $module</nowiki>
 <nowiki>}; done</nowiki>
 <nowiki># this may need to be higher if your disk is slow to initialize</nowiki>
 <nowiki>sleep 4s</nowiki>
 <nowiki># mount the usb stick</nowiki>
 <nowiki>mount "$boot_dev" /mnt</nowiki>
 <nowiki># if everything looks ok, do the pivot root</nowiki>
 <nowiki>[ -x /mnt/sbin/init ] && {</nowiki>
 <nowiki>  mount -o move /proc /mnt/proc && \</nowiki>
 <nowiki>  pivot_root /mnt /mnt/mnt && {</nowiki>
 <nowiki>    mount -o move /mnt/dev /dev</nowiki>
 <nowiki>    mount -o move /mnt/tmp /tmp</nowiki>
 <nowiki>    mount -o move /mnt/jffs2 /jffs2 2>&-</nowiki>
 <nowiki>    mount -o move /mnt/sys /sys 2>&-</nowiki>
 <nowiki>  }</nowiki>
 <nowiki>}</nowiki>
 <nowiki># finally, run the real init (from USB hopefully).</nowiki>
 <nowiki>exec /bin/busybox init</nowiki>

Make sure your new /sbin/init is executable: 

 chmod a+x /sbin/init

If it mounts correctly it will look like this:

 <nowiki>root@OpenWrt:~# mount</nowiki>
 <nowiki>/dev/root on /mnt/rom type squashfs (ro)</nowiki>
 <nowiki>none on /dev type devfs (rw)</nowiki>
 <nowiki>none on /proc type proc (rw)</nowiki>
 <nowiki>none on /tmp type tmpfs (rw,nosuid,nodev)</nowiki>
 <nowiki>/dev/mtdblock/4 on /mnt/jffs type jffs2 (rw)</nowiki>
 <nowiki>/jffs on /mnt type mini_fo (rw)</nowiki>
 <nowiki>none on /dev/pts type devpts (rw)</nowiki>
 <nowiki>none on /proc/bus/usb type usbfs (rw)</nowiki>
 <nowiki>/dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/mnt/disc0_1 type ext3 (rw)</nowiki>
 <nowiki>/dev/scsi/host0/bus0/target0/lun0/part1 on / type ext3 (rw)</nowiki>

* Actually the disc0_1 line may not be correct.  Unconfirmed if this is the result of a previous attempt to mount that is "stuck" in mtab.

* If booted from the USB flash drive, then packages installed by ipkg will go on the usb drive anyway.  If the system boots failover to the internal flash, that package will be absent.

If everything went alright, you will not have to change your root password, and when you execute a 'ipkg list' you will see all of the packages from the database, which would otherwise have been absent.  Use 'ipkg status' to show installed packages.

== DNS and DHCP ==

The Asus WL-500gP has internal DHCP capabilities.  Using the nvram option the Asus router own DHCP server can be enabled, however, to make the router respond to dns queries as a caching names server you should use dnsmasq instead.

Disable the router dhcp server and enable dhcp assignment via dnsmasq.  To use dnsmasq simply edit the following file:  /etc/dnsmasq.conf  I used dnsmasq.conf instead of nvram.  I wiped the S60dnsmasq file and created my own.  My init script for dnsmasq contains only the fillowing line:

 killall -9 dnsmasq ; dnsmasq -K -I vlan1

My /etc/dnsmasq.conf contains the following:

 <nowiki># filter what we send upstream</nowiki>
 <nowiki>domain-needed</nowiki>
 <nowiki>bogus-priv</nowiki>
 <nowiki>filterwin2k</nowiki>
 <nowiki>localise-queries</nowiki>
 <nowiki></nowiki>

== Configuring dnsmasq to use different IP ranges for wired and wireless ==

Firewall initialization by running a startup script in /etc/init.d 
Next it calls the user configuration file /etc/firewall.user 

To better understand the firewall rules I will document notes about them in this section.

Starting with /etc/init.d/S35firewall


== OpenVPN Installation and Configuration ==

First, install the package and then generate a static key file /etc/static.key

 ipkg install openvpn
 mkdir /etc/openvpn
 openvpn --genkey --secret /etc/openvpn/wlan.key

Other guides advise the installation of openssl, lzo, and kmod-tun, however, I found them to already be installed.  Allow OpenVPN connections from the Wifi to the LAN - rules need to be added to firewall.user.

 iptables -t nat -A prerouting_rule -i br0 -p udp --dport 1194 -j ACCEPT
 iptables -A input_rule -i br0 -p udp --dport 1194 -j ACCEPT

The tunneling module

 insmod tun
 echo "tun" >> /etc/modules

Now /etc/modules should look like this:
 wl
 tun

Create /etc/openvpn/wlan.conf

 dev tap0
 proto udp
 port 1194
 keepalive 10 120
 ;comp-lzo
 status openvpn-status.log
 secret /etc/openvpn/wlan.key
 persist-key
 persist-tun
 verb 6
 max-clients 10

''note: I have tried "proto tcp-server" using tcp protocol.  It is much slower than using udp.  For some people udp won't work and therefore they have to use tcp.''

Create /etc/openvpn/makebridge

Some modifications to the iptables firewall /etc/firewall.user

 iptables -t nat -A prerouting_rule -i br1 -p udp --dport 1194 -j ACCEPT
 iptables -A input_rule -i br1 -p udp --dport 1194 -j ACCEPT

== WPA Wireless Security ==

Enable WPA Wireless Security (as opposed to WEP)
# WiFi Protected Access (WPA) is the new security standard adopted by the WiFi Alliance consortium.
# nas is the proprietary binary tool that sets up dynamic encryption (WEP/WPA) on the wireless device.

To use WPA the NAS package must be installed.

 ipkg install nas

 nvram set wl0_auth_mode=""		was wl0_auth_mode=open
 nvram set wl0_akm=psk			was wl0_akm=none
 nvram set wl0_crypto=aes+tkip	was wl0_crypto=tkip
 nvram set wl0_auth=0			was wl0_auth=0
 nvram set wl0_wpa_psk=yoursecretp	was wl0_wpa_psk=""
''(replace yoursecretp with a password of your choice, I used something with letters, numbers, and symbols)''

 nvram commit

Note:  I chose to use PSK instead of PSK2 because PSK2 is not supported on my WinXP laptop OOB without updating something (probably wifi related driver).

The startup script for NAS has to be modified for our interface configuration.  It defaults to br0, but with our setup our wifi is on br1.

 vi /etc/init.d/S41wpa

Replace all references to br0 with br1.  There should be two references.

Line 7:  brctl show 2>&- | grep "${real_ifname}" >&- 2>&- && ifname=br1

line 86: [ "$ifname" = "br1" ] && exit

When the NAS service is running, doing a ps ax should show the process:

 /usr/sbin/nas -P /var/run/nas.lan.pid -l br1 -H 34954 -i eth2 -A -m 4 -k yoursecretp -s icarus -w 6 -g 360
