I won't argue that I may have misunderstood what was really happening, and why. I very specifically remember having to do that. I didn't invent it - I found it at several sources on the 'net (can search again, I suppose, if need be), and it saved me. Right or wrong, that's what I did, and it worked. To that end, what's the real story, and how should it be expressed? Are these two items that we've separated here, so closely related as to warrant a single answer? (Would have been better for me to have not posted, but oh well. I was hoping for such, since I did such a poor job of this. You are either misremembering, or simply didn't understand the effect of the actions you were taking.Ĭorrections welcomed, and accepted. So while you may have gotten things working, it wasn't because of how you explain it. LAN-side, PC-to-PC, no such action is required I had to investigoogle, and that's the solution I ended up with.Įdit: to remotely connect from the Internet, you'll need to set up port forwarding in the router. Sorry if that's a terrible description but that's what I had to do when installing a router for a relative who had Comcast and, understandably, didn't want to pay them a ridiculous amount (any amount over $1 is ridiculous, actually) to set things up for additional PCs on a wireless network. LAN-side, the router will then reply with the expected, private-range IP address and host name resolution. Then modify that PC's settings to point to the router, rather than to the cable modem, for gateway, DNS, DHCP. If you installed a router, you'll want to give it the original PC's mac address (they all have options for that in the admin interface) so that the public IP will be transferred to it instead of the PC. If you did your own network installation (as opposed to having Comcast do it), that is still in effect. Therefore, unless/until you change that, that's how that PC will resolve as long as you are using the modem for gateway and DNS. ipconfig and other tools will show a public ip address and host, rather than a private one. On single-user (single PC) installations, Comcast initially has the public-facing IP address of the cable modem transferred to that PC. This will sound more complicated than it is because I don't know how to express it.
