From DD-WRT Wiki
The goal is to separate the WLAN and LAN ports from each other using the v24 GUI.
[edit] Configuration
Informal Description: I wanted to create a firewall that would have a separate WLAN from LAN. The WLAN would be unsecured (no WEP, no WPA) so as to allow my poor-but-attractive female neighbors access to the Internet without exposing my private network.
I wanted to block outbound mail ports on the WLAN to preclude roaming spammers from using my unsecured WLAN as a launching pad to send their spam.
I also wanted to make sure that several services I run (i.e. ssh, dns, ntp) were forwarded to the appropriate machine on the internal network.
