-# 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.
-
-# step
-1.  run udp2raw_arm  as usual, except you must change the -a option to -g
-```
-./udp2raw_arm -c -r 44.55.66.77:9966 0l 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 0l 0.0.0.0:4000 -k1234 --cipher xor -a
-```
