[HOWTO] Wi-Fi Tethering on MIUI

[k40u]

Start the rom's wifi tether from Settings > System > Tethering & Portable Hotspot > Portable Wi-Fi hotspot.
You should be able to connect to it, but you won't be able to use the Internet.
Now set up the NAT manually, for which which I've found a tutorial online*. We'll want to connect ppp0 to wl0.1.
Open a root shell and enter the following. (Note that /proc/sys/net/ipv4/ip_forward is set to 1 automatically when we enable the rom's tethering)

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -i ppp0 -o wl0.1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wl0.1 -o ppp0 -j ACCEPT

Now you'll be able to access the Internet from your computer.

Disclaimer: I haven't tried turning it off yet. I assume you just remove the three rules and then turn off the rom's tethering.

*new users can't post links, so just Google "linux nat"

Barnacle works fine for me, without any mods.

This works great. Is there any way to make these commands happen each time at startup? (Settings are lost on reboot)

Also does this have to run after wireless tether is enabled? Or does that not matter.

ON miui rom?

Yes. Both MIUI and CM7

Yes. Both MIUI and CM7

Can you post details for CM7 here

I tried but never got it working. Exact steps would be appreciated.

Thank you.

Add them to init.rc

i tried putting the commands in the init.rc under "on boot" but when i rebooted the file reverted back to what it was before i edited it and the backup of the original file i made was gone (init.rc.bak). can someone help me do this? i think the built-in tethering is just more convenient to use rather than installing barnacle and i'm hesitant to use it anyway cuz wifi tether didn't work for me

edit: i guess barnacle does work but i would still like to get this working if it doesn't get fixed in the next update

Does anyone happen to have any insight on this? I know this is an old thread...but I agree with this dude.

You need to unpack and repack the boot.img to make it stick. The init.rc is inside that.
