Grab latest rolling iso from https://downloads.vyos.io/?dir=rolling/current/amd64 I will use vyos-1.2.0-rolling+201903200337-amd64.iso

You can install VyOS on dedicated physical device or use virtualization. I prefer second option Setup VM with one NIC facing dedicated network with your current router.

Boot VM with downloaded .iso file

Login with vyos/vyos

Install VyOS image to disk

install image

It is pretty simple so I will not cover this in my guide. Reboot when you finish.

Configure IP address, default route and ssh. 10.224.30.241 is IP address of router in dedicated network segment

configure
set interfaces ethernet eth0 address 10.224.30.242/30
set protocols static route 0.0.0.0/0 next-hop 10.224.30.241
set system name-server 10.224.30.241
set service ssh port 22
commit
save

Now you can connect using ssh

If your VyoS is virtual, then delete ttyS0 to get rid of annoying message in syslog configure delete system console device ttyS0 commit save exit reboot

Add Debian 8 repo (it will disappear after reboot)

sudo su
cat << EOF >/etc/apt/sources.list
deb http://archive.debian.org/debian/ jessie main contrib non-free
EOF
apt-get -o Acquire::Check-Valid-Until=false update

Install your favorite text editor

apt install vim nano mc

Install v2ray

bash <(curl -L -s https://install.direct/go.sh)

You may need to use proxy server to connect to install-direct. In this case I use v2ray client installed on another computer

bash <(curl --socks5-hostname 10.224.30.6:1081 -L -s https://install.direct/go.sh)

Configure v2ray

nano /etc/v2ray/config.json
