Restrict user access on external router port
Posted on 2008-09-30
I have a small problem. Linksys Router with 4 ports. I have an existing 10.x.x.x network. The gateway for my existing network is 10.0.0.2
i want to add a router into my network and provide customers internet access. They will be on the LAN side of the router. My network on the WAN side of the router. I can make their network any number scheme. Here is the router ip setup as of right now.
ip address: 10.0.6.1
subnet mask: 255.255.0.0
dns 1: dns server on my network
dhcp scope: 192.168.1.100 - 192.168.1.150
Everything is working fine. I can get to the internet. BUT HERE IS THE PROBLEM:
I CAN PING AND ACCESS EVERYTHING IN MY LOCAL NETWORK (10.x.x.x) from the LAN side of router!?!?!
How do I keep internet access to users on the lan side of the router and block them from accessing the WAN side of the router but still provide internet? I have to install this system in like 4 hours. ANY HELP WOULD DO!
Thanks all for your time and efforts in advance.
