I found a information about, that consists in adding iptables rules by commandline to your rooted device. I tested it on my android 4.4 on Blu studio and works fine.

Quote from xda-developers:

1. You need a rooted device 2. Make sure you have a VPN app, like OpenVPN or DroidVPN ( I use DroidVPN and its the best) 3. Download Terminal Emulator 4. Activate your hotspot and connect to your VPN 5. Launch Terminal emulator and on the first line type "su" (without the quotes) and press enter 6. Copy and paste this to the Terminal Emulator, MAKE SURE TO PASTE TO A NEW FOLDER USING ROOT BROWSER FIRST, AND COPY TO T.E. IN THE EXACT FORMAT AS SHOWN

iptables -t filter -F FORWARD
iptables -t nat -F POSTROUTING
iptables -t filter -I FORWARD -j ACCEPT
iptables -t nat -I POSTROUTING -j MASQUERADE
ip rule add from 192.168.43.0/24 lookup 61
ip route add default dev tun0 scope link table 61
ip route add 192.168.43.0/24 dev wlan0 scope link table 61
ip route add broadcast 255.255.255.255 dev wlan0 scope link table 61

7. That's about it Also be sure to make a folder with Root Browser and paste the code there, as this resets after re-boot. Please comment if this worked for you, it worked on my LG G3 on android 4.4.2

ATTENTION: Part of the rules where it says wlan0, this is interface that corresponds to where you want send the connection. To send it to the WiFi hotspot, replace it with ap0 The tun0 is the VPN tunnel that you receive from the remote server. You can list all the interfaces typing netcfg the root terminal

To terminal emulator i use ConnectBot:

ConnectBot allows a terminal emulator on your device for connections ssh, telnet and localhost.

I found some information that consists of adding iptables rules using command-line in your rooted device.

I tested it on my Android 4.4 on Blu studio and it works fine.

Make sure to paste to a new folder using Root Browser first and copy to T.E. in the exact format as shown below:

iptables -t filter -F FORWARD
iptables -t nat -F POSTROUTING
iptables -t filter -I FORWARD -j ACCEPT
iptables -t nat -I POSTROUTING -j MASQUERADE
ip rule add from 192.168.43.0/24 lookup 61
