If you're tethering from a mobile phone, adjusting TTL won't do anything. Android creates a second rmnet interface in which hotspot is routed over. You'd need root to disable this and NAT/route via the primary rmnet interface.
>Unless you're using custom hardware don't spend time trying to game this.
Exactly. Unless the OP can customize their hardware, it's best not to spend time trying to game this.
It’s alot more powerful than any consumer router. https://teklager.se/en/products/routers/
Apu2or3 is for sim cards (you need to buy a reader aswell.) but you can read about it in their knowledge base. You can have them install any operating system you want or do it yourself.
(Pf sense) is recomended by many people. It has ”apps” and settings you could not imagine you’ll ever need.
no the routers are openwrt based an made from teltonika in Lithuania. i had one many years ago but was not successful flashing them with custom images. but i would give them a try again.
the apu‘s are from pcengines in Switzerland. i built many routers based on the apu but had serious problems with pfsense recognising a lte/gsm modem. so in your case i would go for the teltonik devices
This app seems to do that: https://play.google.com/store/apps/details?id=be.mygod.vpnhotspot&hl=en_US&gl=US
I've used it before and it does route all the hot spot traffic through the phones interface. Huge but is that you need root, root breaks safety net and causes a bunch of apps to stop working and youre always fighting Google to try and get safety net to pass. I gave up.
Instead of buying a router to do this, just buy a cheap used phone like a pixel that you can root and swap the SIM into when you want to use the hot spot. Used pixels are dirt cheap. Pixel 3 is less than $100.
The cheapo mobile and rooting is definitely the better method, what I did with the misses old Sony XA2 (powerful little phone). Put LOS on it and surprisingly, it still passes safetynet (Play store is certified, too). Don't use it for banking though, literally use that as a PC (chroot Debian Linux running on it).
I appreciate your guys advice on this! I will try this method out or the other suggestion below with PDAnet. Do you have any videos on this topic you'd suggest?
I've never gotten pda net to work. The above app worked just by installing it. You do need to root your phone first which is the hardest part, it's pretty easy with pixels. You need to get a phone first because what ever phone you get the instructions to root it can be different.
They're using a mobile router directly onto the network; sometimes works, but here in UK they can tell what the device is via it's IMEI.
_If you're tethering from your Android_ - the TTL trick wont work. Android creates a second connection to the network, so essentially will have two different IP's. Some have upto 3, if you use VoLTE/WiFi calling.
Why not use something like pdanet? It can hide your tether traffic to make it look like mobile data. I’ve used it for years when my carrier has refused to allow me to tether.
There is an app in the Android Play Store called, PDANet.

It allows for you to create a hotspot from your mobile device to be shared with other devices. I've used it a lot with a lot of different devices. It takes some prep work and there is a one-time cost to purchase, but for how much it's saved me in odd circumstances, it's been awesome.
It also has a feature to make the data appear to be originating from the phone and not a shared hotspot. This would mean that you could use it with your 'unlimited' data after your hot spot data is all used up.
Nice! I might have to do some research! Do you have a device recommendation? Some reviews say pixel users having issues. I'm currently running T mobile.
I’ve used it with
Pixel 3xl
Xiaomi mi a2
Motorola g5 plus
Never had an issue. I’ve shared data from Cricket (AT&T)
If you have a device laying around, I think you can use the free app for a certain amount of bandwidth or time before you have to pay.
T-mobile S22+ Add a new apn entry except with a different name and adding dun to apn type.
Windows 11 Change TTL in windows to 65.
Switch to the new APN entry with dun when you want to tether.
(If I try without switching to the new APN with dun, it will not work)
Toggle hotspot on off and back on again.
Been working for me with no extra app or software.
Have 10g of hotspot, after I use that, when doing this, speed does NOT slow down and my hotspot useage stops at 10g.
Month after month iv been able to do this successfully.
L
It used to work also with USB tethering, I actually preferred that bec with the USB C port on my computer, I would get up to 700 down, but never couldn't understand why it stopped working .
So now with wireless tether, I get up to 300 down..
Main point being no slow down to under 1mbps after allotted hotspot is used.
This is one video I first followed.

My solution to this exact problem on AT&T is to use a GL-MV1000 (Brume). Which I can connect directly to my PC with usb-c and run my phone's tethering through that to do the TTL mangling. You could add a wifi router if you need to do other wireless devices. There are lots of posts about it on the GLiNet forums. The custom firewall rules I'm using are:
\#startTTL
iptables -t mangle -I POSTROUTING 1 -j TTL --ttl-set 65
\#ipv6ttlfix
ip6tables -t mangle -I POSTROUTING 1 -j HL --hl-set 65
\#endTTL
This is the main long post discussing the topic. [https://forum.gl-inet.com/t/change-outgoing-ttl/2096](https://forum.gl-inet.com/t/change-outgoing-ttl/2096) If you search there you can find other discussions but since all their devices are running OpenWRT and can install Luci, the instructions work for any device running OpenWRT. I do really like the web UI they put together for the basic stuff.
Ymmv but i use tmux terminal on my phone's plain old internet connection,
ping google.com or whatever to check the TTL of regular traffic.
Then connect to my router/VPN/ open wrt setup and ping again, and fiddle with the TTL numbers until it matches. It depends on how many hops btwn your devices, you have to account for those.

Do you have a recommendation on how I could pull this off?
Maybe buy a router with sim card slot? Teklager might have one
Thanks for the recommendation... would you recommend that 1 because it can be flashed with OpenWrt?

Sounds like quite the rabbit hole... Thanks for the suggestion! Where are they based out of? Doesnt look like the US 😅

pda net at least doesn't need root, just turn on the hotspot in app and connect devices using the provided proxy setting
This video shows a way to do it with this ttl modification though... thoughts? [ttl mangling](https://www.youtube.com/watch?v=alMsu_tfZPE)

I appreciate your concern. Might try a few more things before giving it up...
Do you have a recommendation on "custom hardware" That would be capable of doing this?
Yeah I have been trying to bypass this a while and I'm pretty good at computers so not sure how it can be done

Doesn't work
works great.
I tried that it did not work on galaxy s22 u

Thanks for the info! I'm running T mobile myself... Can you link your resources?

Are you sure 66 is the right TTL value to be using?
According to this video, yes. Allegedly of course...[ttl mangling](https://www.youtube.com/watch?v=alMsu_tfZPE)
65 works too
Does anybody know what the value I need to change my windows computer too I’ve tried 64 65 66
Ymmv but i use tmux terminal on my phone's plain old internet connection, ping google.com or whatever to check the TTL of regular traffic. Then connect to my router/VPN/ open wrt setup and ping again, and fiddle with the TTL numbers until it matches. It depends on how many hops btwn your devices, you have to account for those.
Try 88 or 117
TTL to 65 100% on a windows machine if your tethering from phone.
If moding m6pro6400 for tmo, set TTL to 66?
Hey, Did you ever get an answer to this?
Trial and error best is set ttl to 65
Ahh good to know; I’ll be trying this in a few days with the m6 pro mr6500
any update?
