question
#1

I am using outline app in android mobile for voip traffic but be default it is forwarding all traffic to shadowsocks server…
But i want to forward traffic to server for only one IP address for my voip server and everything else should go through normal Internet.

But i want

Android traffic for 1.1.1.1 -> shadow socks server -> voip server

All other traffic should go like

Android-> Internet
