PAP2T vs RT31P2

Why would he be getting a 172.xx address off the LAN side of his WRT router to his (XP) computer. Unless he made changes the "normal" IP generated on the lan side would be in the private 192.168.x.xxx range. I've never seen a router (out of the box) generate a public IP on the LAN.

172.16.0.0 - 172.31.0.0 are class B private networks. 192.168.x.x is class C and 10.0.0.0 is the Class A. All three are private subnets and are not routable on the internet.

Most of the routers are set to give a subnet in 192.168.x.x. I think the user must have changed it to the class B private address.

Yes, I realize that, but the thread read like "who's on first and what's on second" and I didn't see anywhere where he changed the router default (and have no idea WHY anyone does that on the LAN side as it makes no difference) but obviously he did. Also I now see he is plugging his laptop into the VOIPO device which gave him the 192 address which confused me as well. The thread had my head spinning with WRT RT WRT RT . I prefer "voipo device" and "WRT router" just for clarity (I did tech support training for an ISP and we preached clarity as the key with end users) .

Anyway, I should have kept my mouth, er, keyboard, shut.
