I am relatively new to Tomato firmware in general and currently have installed Tomato Firmware v1.28.0498 MIPSR2-Toastman-VLAN-RT-N K26 USB VPN-NOCAT with a basic functional configuration on a Linksys E4200. I have some experience setting up a Guest Wifi with DD-WR, but have not been able to figure out how to do this on Tomato yet. Is there a tutorial or a thread that tells you how to setup a guest wifi network and isolate it by only allowing WAN (internet) only access?
Never mind: I found a link which I am unable to post yet which helped. It does not tell me how to block services on the router from the guest network such as the media drive, FTP etc..
