ATT Still Showing Hotspot Data as used

Hello,
I am using merlinwrt on an asus router with a phone tethered for internet. On Verizon I spoofed all ttl to 65 and I was able to bypass hotspot throttling fine. However, on AT&T even with the ttl at 65 it is still showing as hotspot usage under my at&t app. I tried using the built in bypass options the firmware has, that sets everything to 64 and extends anything with a ttl of 1 to 64 but that didn't seem to work either.
Is my only hope to use a computer and pdanet and connect that to the router?
Thanks

After messing around with a rooted pixel 4a 5g for awhile I've got settings working and it seems to not count towards hotspot data! I now have nice 5g tethered to a good asus router, if anyone is interested in this let me know and I'll try to share details on how it's done.

Do share! Make a tutorial posting

Most likely the hotspot data is leaking through IPv6.
Try this:
Go to Modem > Connection Profile > copy and paste the following:
Custom DNS Server1: 1.1.1.1
Custom DNS Server2: 1.0.0.1
Custom DNS Server3: 2606:4700:4700::1111
Custom DNS Server4: 2606:4700:4700::1001
Click Save&Apply.
Go to Network > Firewall > Custom Rules > delete the entire page, then copy and paste the following:
iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 65
iptables -t mangle -I PREROUTING -i wwan0 -j TTL --ttl-set 65
ip6tables -t mangle -A POSTROUTING -o wwan0 -j HL --hl-set 65
ip6tables -t mangle -I PREROUTING -i wwan0 -j HL --hl-set 65
Click Restart Firewall.
After you reboot the router, the DNS values may not be displayed, but they are saved.

Question: Would that be wwan0 or usb0? Since it is a tethered setup. I'm having the same problem.

Hi all, I'm still burning hotspot data and need some help. Tethered Android phone on AT&T postpaid plan, Raspberry Pi with Goldenorb. I'm using the settings from Bill A and also his Tethering Guide from another post. I've attached two pics of my settings. I was able to successfully do this on Verizon, but can't get AT&T working. Any help would be appreciated!

May need to modify the ttl and hl on the phone itself

I didn't know that was possible. Can you point me to a thread on how to do that? Thanks.

I have tried everything I can find to try, but cannot get the tether to use phone data, just keeps burning hotspot data. I tried TTL/HL of 64,65 and 66. With IPv6 enabled and disabled, with custom DNS servers and without. Nothing works.
I finally gave up and took the SIM out of the phone, popped it in my EM160, set the TTL to 64 (IPv6 disabled) and its now using phone data. I have no idea why, but I'll take it. I would prefer to use the EM160 anyway because its faster than the phone.

I'm trying to do the same thing with a Pixel 6 pro on AT&T and merlin on RT-AX88U. I have tried "Extend the TTL value" - Yes, with" Spoof LAN TTL" both yes and no. Both configurations still burn Hotspot data. I have IPV6 - disabled in the settings.

likely the phone itself is setting the TTL/HL before traffic exits the phone to the network. You may have to mod the phone for this.

Something like PDAnet or tethering enabler for Magisk?

I'm not a phone guy. No clue how to do it. I just know the phone is the host to the modem and I believe it is setting the TTL and HL on all traffic that it sends out to the cell network.
