How did you configure your NAT box and internal network? We need more information about your current configuration.

Hello Brent, Most likely your RRAS configuration is not set up correctly. Check in RRAS that you have chosen the correct interfaces assigned to the Public and Private roles. Your Public interface is that one that is connected to the internet and your Private is the one connected to your internal network. Once you have that working correctly, you should get the same IP NAT'd for your internal hosts. You can use this website to check your external IP address: mysourceip.comVisit my blog: anITKB.com, an IT Knowledge Base.

Can you ping an IPaddress on the internet from your machines behind the nat? 74.125.19.95 is the IP for google. If it pings, then you need DNS. Note that NAT blocks auto configuration from ISP. YOu need to have your NAT (if it has built in DHCP server) assign DNS servers to your clients. Or you can have a stand alone DHCP server do it, or you can configure DNS manually on your clients. If it doe not ping. Look over your NAT configuration again until you can ping.
