NAT problems with WRVS4400N

[Mark Alley]

I have a WRVS4400N configured pretty much default with the DMZ turned on. My ISP has contacted me and says that my Private IP's are being routed to the Internet. I cant make an sense of this since everything seems to be up and working. I was thinking that the Internet would not work at all since private IP's are supposed to be dropped once they are on the Internet.  Any ideas?

Firmware version 2.0.2.1

Hi Mark, what is your LAN IP address behind the WRVS?

Thanks Tom! I should add I am using a Static IP for the WAN side.

Yeah, not sure what they mean your private is routing out. It is possible for private IP addresses to be routed... but that happens very rarely when someone messes up on the ISP side... So long as the router is operating in "Gateway" mode, you're going to be NAT'd.

I personally wouldn't think anything of whatever you were told (at this time) unless it comes up again.

Thanks Tom,

You were exactly right! Turns out his problem was coming from an entirely different source than he thought.

Thanks again for your help!
