This is where I write some tips that I may need later, you may need them too

Wive(-NG) Configuration

Siavash Safi — Fri, 08 May 2009 19:08:52 +0330

I wrote about Wive in the previous post. I'm going to write about the configuration in this one. But first I should tell you about Wive-NG which is the next generation firmware. I highly recommend upgrading to wive-ng. The upgrade can be done as I described it in the previous post (make sure to reset the device after that). The only difference is the default ip address which is set to: 10.200.200.249.

First you should connect to the router using ssh or any ssh client you like:

$ ssh root@10.200.200.249
root@10.200.200.249's password: 
::Wive-NG-0.2.21::RTL8186-REALTIME::
Base station firmware version
Enter 'menu' for config router
Sun, 26 Apr 2009 18:41:28 +0700
[Wive-NG@/]#

Note!

The default password is rtl8186, don't forget to change it.

Running menu will show you the configuration menu:

-=General menu=-
	
1) Boot 2)Interfaces 3)General 4)WPA 5)Stat 6)Scan 7)RSSI 8)ExtendedMenu
9) Change password 10) WiFi reset 11)Save 12)Reboot 13)Quit
	
Enter choice number:

Enter a number and the related configuration file will be opened using vi. The configuration files are all documented using comments.

Important!

Don't forget to save the configuration by entering 11 or all the settings will be lost after reboot!

It's not possible to describe the configuration in detail here since there are many ways to configure the router which depends on how you're going to use it.

You should know about basic linux networking in order to be able to do the configuration. If you don't you can ask in any linux forums and/or irc channel related to networking. Wive-NG has a wiki but unfortunately it's in russian, you can use google translate

If you have any problems/questions related to configuration, feel free to ask here

Networking

Siavash Safi — Mon, 13 Apr 2009 15:55:25 +0330

iptables

sharing an internet connection

eth0: connected to internet

wlan0: local WLAN

# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
# iptables -A INPUT -i wlan0 -j ACCEPT
# echo 1 > /proc/sys/net/ipv4/ip_forward

Full NAT

# iptables -t nat -A POSTROUTING -j MASQUERADE

MAC Address Filtering

Filter (Used with FORWARD here) all incoming traffic from wlan0 and outgoing to eth0 except the specified MAC address (can add more MACs using the same command)

# iptables -P FORWARD DROP
# iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
# iptables -A FORWARD -i wlan0 -o eth0 -m mac --mac-source xx:xx:xx:xx:xx:xx -m state --state NEW -j ACCEPT
