Fiber internet and shields up test

[techronin]

Just upgraded from dsl to fiber. My isp put a box on the outside and connected it to the inside with cat5 I just plug directly into my wireless router (or computer). Wondering if when I run a shields up test it's testing my router that I can configure or the box outside/connection at my isp that I can't.

Congratulations! That's odd I take you just got internet, no TV then?

Who is your service provider?

I have Fiber through Verizon FiOS, they use a standard ONT unit at the property that takes the fiber line in, and converts to Ethernet. The ONT has no real processing ability, everything Verizon does is through their provided router, if you use your own router verizon loses the ability to trouble shoot (since their router has a backdoor for them to do diagnostics).

So if it's anything similar to FiOS ONTs, the box outside does NOTHING besides turning your fiber into ethernet for your use.

Ty. No I just have telephone and internet.

Yea mine is like that the ONT is outside and the power supply for the ONT is inside. Difference I guess is I have TV and they used existing coax from the ONT into the house, split it, then one to the TV and one to the router. When I first got FIOS I was getting a zero ping with it on Speednet.

FiOS no longer does Coax installs, it's still used for TV service, but all installs are pretty much done with ethernet at this point. This also fits with their new set top boxes they've been doing trials of with some customers IPTV service, purely done via ethernet. No Coax at all.

It's required for anything over ~100mbps anyway.

And yeah, I still get 2-3ms ping to 3-4 different speed test servers in the area, also managed to get a solid 2ms ping to some counter strike servers the other day. Usually it's 5-20ms, 2ms was a new low, and it stayed at 2ms for a full 45 minutes.

My ISP is a local telephone company. They sell 2 different wireless routers in their retail stores but don't configure or set them up. Thanks for the information - very helpful.

Shields up test shows responding to ping even though it's turned off in cheap wireless router I have as well as open port 22.

My guess would be it's their router, but without knowing the model of the router, or the model of ONT, and the ISP itself, I can't really make a more educated guess.

Ran mine like that as well.

... cat5 I just plug directly into my wireless router (or computer). Wondering if when I run a shields up test it's testing my router that I can configure or the box outside/connection at my isp that I can't.

Does that "shields up test" show what it thinks your IP address to be? (I presume that the test executes on some outside server and probes your apparent address.)

What IP address does the device (that you plug into the cat) get? If the shield test sees the same address, then there is no NAT upstream of you.

You can use tools like traceroute to show (some) routers that are between your PC and some distant site (like AT).

Whether the upstream is just modems/bridges/switches or routers, it can always filter the traffic. (Even a bridge with no IP address can still block traffic selectively.) To test your router's exterior you must connect the probing device directly to the WAN-port of the router.

I see. I'll also run the test without the router but straight into my computer and see if I get the same results. Thanks.

Same results without the router. When the test runs it matches the "external ip" that shows up on the traceroute (ping tools ap) not my router's ip. So I guess the shields up was probing that and not my router.
