Thanks for very helpful answer. My aim is not to proxify my PC internet traffic system-wide, but only for example my web browser traffic so i set 127.0.0.1:v2rayport, i am guessing it will work like that out of the box.
On the server i installed using command mentioned at GitHub - v2fly/fhs-install-v2ray: Bash script for installing V2Ray in operating systems such as Debian / CentOS / Fedora / openSUSE that support systemd
Then i had to manually define config.json files content:
Shadowsocks | V2Ray Beginner's Guide
server: /usr/local/etc/v2ray/config.json
client: /etc/v2ray/config.json
and restart at both ends: systemctl restart v2ray
and it works under the defined ports. I am wondering if i could do it easier. I have set two servers in single config.json and it appears that it from time to time switch between the two automatically, wondering if i can influence this switching manually or make one default and other fail-over or if/how load balance under shadowsocks protocol works - i do not insist to use SS protocol, that is just what i have used before)?
