Question

DNS configuration for static IP

by Dec 1, 2015 1:59PM PST

Hi, I'm using Cisco RV082 as external firewall for my computer (and NAS) and the system looks like this: ISP ==> ZyXEL modem/router ==> Cisco RV082 ==> Computer (Windows 8.1). The problem is that both the Xyxel and Cisco are using the same IP, 192.168.1.1, so I changed the IP for the cisco to 192.168.1.2. I also changed the properties for the Internet protocol on my computer according to ipconfig, see attached image. The problem is that I can't access the Internet and when I ask Windows to identify the problem it says that the DNS-server doesn't respond. So I guess that there is something wrong with my setting but I don't know what to use. I tried 8.8.8.8 but it didn't work and my computer doesn't accept 0.0.0.0, any ideas how to solve this problem? I can access the Internet if I use wifi.

Since you've put a router behind a router, what a mess. Let the makers work it out for you.

Thanks for your reply! I contacted the internet service provider and they turned the router into a switch and now it works!

Not even IP separation between them.

If you run ipconfig /all you can get an interesting readout of IP address assignments. I would suggest leaving the front router (one connect to mode) the same, and change the second router to 192.168.10.1 instead, that way the first router's DHCP addresses will all start

192.168.1.*

and the second router's will all start

192.168.10.*

so that the two don't interfere with each other on the home LAN.

Thanks for your reply, I did try that but the second router can only work in the 192.168.1.x range. I can change the IP of the first router and see if that helps.
