Hi, I'd like to use my WRT54G to give wireless users access to the net by way of my LAN. But I don't want them to be able to access my LAN. Are there any recommended setups to achieve this, perhaps using custom firmware? I have a ADSL modem/router (zyxel) for internett access, putting the network behind NAT. If I plug the WRT54G into this, effectively creating a second layer of NAT, will this prevent users from the second "innermost" LAN (wireless) from accessing the first "outer" LAN, but still allowing internet access via the ADSL modem? Or should I create some kind of DMZ setup, using the WRT54G? Or VLANs? Thanks for any help!
