Support iptables about powertunnel-android

[krlvm]

Have you tried proxy mode in settings?

[hamedsbt]

Yes, but may app does not support proxy settings, such as official youtube app.

Can't you configure iptables manually?
(maybe a stupid question, I'm not familiar with it)

I'm not very professional iptables user too. it may help: https://tldp.org/HOWTO/TransparentProxy-6.html

I think you can use this, but I haven't tested:
iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to 127.0.0.1:8085
iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to 127.0.0.1:8085
To get traffic back execute then:
iptables -t nat -A POSTROUTING -p tcp -d 127.0.0.1:8085 --dport 80 -j SNAT --to-source 127.0.0.1:8085
iptables -t nat -A POSTROUTING -p tcp -d 127.0.0.1:8085 --dport 443 -j SNAT --to-source 127.0.0.1:8085

127.0.0.1:8085 is the default proxy server address, replace it if you've changed it.

Thank you for your try, but I prefer this process handle with app GUI as much as simple and stable.

I don't want to root my device, so I don't think this will be supported in the future.
