# How to run udp2raw on a rooted android device(arm cpu)

There is currently no GUI for udp2raw on android.Make sure you have installed Terminal to run it.

Download udp2raw_arm from https://github.com/wangyu-/udp2raw-tunnel/releases.

Copy udp2raw_arm to any dir of your **internal storage** .Copying it to **SD card wont work**.

# Steps
1.  run udp2raw_arm  as usual, except you must change the -a option to -g
```
./udp2raw_arm -c -r 44.55.66.77:9966 -l 0.0.0.0:4000 -k1234 --cipher xor -g
```

2. find the generated iptables rule from udp2raw's output,add it manually by running:
```
iptables -I INPUT -s 44.55.66.77/32 -p tcp -m tcp --sport 9966 -j DROP
```

3. run udp2raw_ram without -g command

```
./udp2raw_arm -c -r 44.55.66.77:9966 -l 0.0.0.0:4000 -k1234 --cipher xor 
```
