Random HDHR's shown on my.hdhomerun.com

Post by rdoac » Mon Jan 20, 2020 1:58 pm

I can't see my setup - although kodi appears to work.

My subnet is 192.168.2.x None of those device ID's are mine?

Any ideas how to troubleshoot?

That returns any device/engine that connected from the same public ip that you used to view such from (I believe in the past 24, possibly 48 hours). The my.hdhomerun.com site then only displays any tuner from that list that it can actually reach. (so if there is proper routing enabled between subnets, you may actually see devices that are not on your subnet)

Today it seems to be working.

I have had the same public IP for a few months. Am wondering if it's a whole public IP subnet?

I do have some VPN's which I use to manage other networks - but none in those ranges.

So - somewhat confused.

This is happening again. More random devices, more random local subnets. Is there a way to fix this?

Is your ISP using CG-NAT?

Have you used a VPN between the time you did not have the problem, and now, and if so, does it have proper filters to block all traffic from those VPN connections to your external ISP?

I have some vpn's connected to my router - none of which use my router as a gateway. None of those IP's reflect any IP's I'm vpn'd to.

It's Comcast - my router has a public ip - and ipchicken.com shows that IP from my network. (I've had that IP for months now).

Doesn't matter if you could "see" such subnets just that the devices in question used the same public ip (in the past 24-48 hours) to connect to SD that you connected to SD with when you viewed such information. Those devices are behind other "routers" that have connected though such, not directly on the networks you are connected to.

If you connected to SD through any vpn to view such, it would display any device that also used such. For example I use a vpn to company x from my pc (device specific, not router)... others used their router to flow "all" traffic through company x I would only see those others as my devices use my own router's public ip but when I view from that pc, I connect to SD through company x. If I configured my router to put me on that vpn, then within 8 hours my devices would also connect through company x and I would see mine as well as the others. Since company x has dozens of public ip's the next time those devices connect, they may not be using the same ip you are currently using, thus fall off. You also may have inadvertently set something up that there is a route between them and SD connecting through you with a private address space rather than public.

If your router has a vpn configured, you might not be connecting to SD through your public ip. Your devices also may not be connecting to SD through the same ip you are.



Are all of your devices displayed or is the list entirely wrong? As what one is supposed to do with the list returned is attempt to connect to each device on the list and verify it exists before presenting it as a list of devices.

What kind of VPNs are we talking about here? What's weird is that all of those device IDs are for units connecting from Comcast and in the same general area in the country.

It looks like Comcast is IP sharing using a carrier grade NAT or proxy approach.

Try this URL (https) and see what it returns:
https://api.hdhomerun.com/discover

Today is correct and shows my stuff.

[
{
"DeviceID": "1072388B",
"LocalIP": "192.168.2.51",
"BaseURL": "http://192.168.2.51",
"DiscoverURL": "http://192.168.2.51/discover.json",
"LineupURL": "http://192.168.2.51/lineup.json"
},
{
"DeviceID": "1310BED3",
"LocalIP": "192.168.2.81",
"ConditionalAccess": 1,
"BaseURL": "http://192.168.2.81",
"DiscoverURL": "http://192.168.2.81/discover.json",
"LineupURL": "http://192.168.2.81/lineup.json"
},
{
"StorageID": "F58C583A-C572-4642-88FB-E54DAFE63291",
"LocalIP": "192.168.2.10:36515",
"BaseURL": "http://192.168.2.10:36515",
"DiscoverURL": "http://192.168.2.10:36515/discover.json",
"StorageURL": "http://192.168.2.10:36515/recorded_files.json"
}
]

(The discover url is what I was using).

The VPN's are PPTP, and just route subnets - not default gateways. It's just so I can login to sip phones and reprogram them if something goes wrong. I have backup VPN's go to my house in case our work connection goes out.

If there a way from SD's end to see what the public IP's are?

It's a Comcast address in your region of the country, but not one that would belong to a customer.

Are you using an xFi gateway as your router? If so, do you have Protected Browsing/Advanced Security enabled in its configuration?

No, I have my own modem and router. It's a Miktorik, I just pull a lease with DHCP.

For reference - Jason worked this out.

It's Comcasts quota proxy's fault. When you go over 50% of your quota, they inject a banner to let you know the progress. This means that anyone in a region will appear to come from the same public IP (Comcast's quota banner injector proxy) not their actual public ip.
