== Requirements
* Magisk 22.1 (older versions not tested)
* link:https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf#installation[MagiskHide Props Config] module installed
* A terminal emulator; either link:https://f-droid.org/en/packages/com.termux/[Termux] or link:https://f-droid.org/en/packages/com.termoneplus/[TermOnePlus]
- Want to use Linux software? Install Termux.
* AFWall+ 3.5.1 (older versions not tested)
== Optional (recommended) requirements
* Kernel with "xt_HL.ko" module enabled; netfilter's TTL packet mangling
* Busybox Magisk module
.Installing Busybox Magisk module
[%collapsible]
====
. image:MV1iA.png[]
. Search for 'Busybox' to find "Busybox for Android NDK", then install it.
====
NOTE: Testing xt_HL support: +
1. Launch a terminal emulator. +
2. ``su`` +
3. ``iptables -t mangle -A POSTROUTING -o wlan+ -j TTL --ttl-set 64;ip6tables -t mangle -A POSTROUTING -o wlan+ -j HL --hl-set 64`` +
-> If your custom kernel does not support "--ttl-set" and/or "--hl-set", inform them of this repository publicly (to increase exposure of these instructions).
TIP: For kernel tweakers: link:https://web.archive.org/web/20210423030541/https://forum.xda-developers.com/t/magisk-stock-bypass-tether-restrictions.4262265/[A reference for enabling xt_HL support through Magisk].
== 1. Configure props
NOTE: ↵ is the kbd:[Enter / Return] key.
. Launch a terminal emulator.
. ``su``
. ``settings delete system tether_entitlement_check_state;settings delete global tether_dun_required``
. ``props``
** "Select an option below." (4 for "Add/edit custom props") kbd:[4 ↵]
** Select "New custom prop" with kbd:[n ↵]
*** `net.tethering.noprovisioning` kbd:[↵] -> kbd:[true ↵] -> kbd:[y ↵]
** "Do you want to reboot now?" kbd:[n ↵]
** Select "New custom prop" with kbd:[n ↵]
*** `tether_entitlement_check_state` kbd:[↵] -> kbd:[0 ↵] -> kbd:[y ↵]
** Select "New custom prop" with kbd:[n ↵]
*** `tether_dun_required` kbd:[↵] -> kbd:[0 ↵] -> kbd:[y ↵]
***** "Do you want to reboot now?" -> kbd:[y ↵]
== 2. Adjust TTL & HL
."xt_HL.ko" required method (adding network tables rules; the best method)
[%collapsible]
====
. Open AFWall+ -> 3 vertical dots (hamburger menu) -> Preferences
- UI Preferences
** Confirm AFWall+ disable -> Enabled
- Binaries
** Iptables binary -> System iptables
** **[optional]** BusyBox binary -> System BusyBox
* Open AFWall+ -> 3 vertical dots (hamburger menu) -> Set custom script
NOTE: Blanket setting \*rmnet* might be a bad idea? +
rndis* is specific to USB tethering; \*rmnet* still has business with USB tethering, along with all other tether types.
TIP: Put in "Enter custom script below".

== 3. Test for TTL 64 (desired) on the tethered device
* Windows:
- IPv4/iptables: `ping -4 gnu.org`
- IPv6/ip6tables: `ping -6 gnu.org`
If the TTL & HL is 64, you've successfully completed this guide.
If this helped you, spread this guide around; I hate seeing crappy guides at the top of Search Engine results.
