I have a motorola sbg1000 as my home router. This is my isp provided router. I have a couple of ports forwarded for remote desktop and a couple of applications. I'm setting up a test lab network for a number of different security tests. In my test network I have two pcs. I don think you need the specifics on the pc's, but I have that info if needed. One is running windows xp. The other is running windows 7 with vmware that has win2008r2 and ubuntu so far. My router is an asus WL520GU GC E3188. Both are hard wired. I want to have my test network seperate from my home network because of the types of testing I'll be doing, but I can't for the life of me figure out what I'm doing wrong. Right now the Asus is connected to the motorola(isp) router and the internet is running on both. However I've tried a number of different ways to try to seperate the Asus router into it's own network but failed. I'll try to offer any information that might be helpful. I'm just not sure what it would be. I have an intermediate skill set with computers but newbie to networking. Any help would be appreciated.
