There is currently no GUI for udp2raw on android.Make sure you have installed Terminal to run it.Your device has to be rooted,otherwise you cant use raw socket.
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.
- 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
- 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
- run udp2raw_ram without -g command
./udp2raw_arm -c -r 44.55.66.77:9966 -l 0.0.0.0:4000 -k1234 --cipher xor
zoom-in if not large enough
