    So, let me explain my set up:

    I have a Cisco 2610XM router picking up internet from a fiber optic T-1. I have a NAT overload on the Cisco 2610XM. My LAN is usin ip range with being the router.

    I have hooked up a Linksys WRT54G Wireless Router to my switch on the LAN to serve as a hot spot. I've set the router to be:


    The internal network for this router is using

    The problem is that the wireless users on the Linksys WRT54G can ping and access internal ips of the larger subnetwork of the Cisco router. For example, a wireless user can ping and even connect to it by usin the ip address. I do not want them to be able to access anything ouside of the range and of course, internet. IE, I don't want the subnet mask to be able to ping or access machines in the network.
