gwhosts

Route the list of hosts through the specified gateway (e.g. VPN).

🚀 Run it manually, using cron, or any other way.

How does this script work

1. Resolves IP addresses for hosts specified in a file;
2. Combines similar addresses into subnets;
3. Adds resulting subnets into static routes via specified gateway.

Installation

LT-Version (RECOMMENDED)

✅ The lt-version has no external python dependencies and does not use argparse. So it starts up to 10x faster on slow devices like OpenWRT routers.

curl https://raw.githubusercontent.com/SharUpOff/gwhosts/main/dist/gwhostslt.py -so - | sudo tee /usr/local/bin/gwhostslt > /dev/null

sudo chmod 755 /usr/local/bin/gwhostslt

PR2-Version (SLOW)

⚠️ The pr2-version uses pyroute2 (if installed) and argparse. So it starts up to 10x slower on slow devices like OpenWRT routers.

curl https://raw.githubusercontent.com/SharUpOff/gwhosts/main/dist/gwhosts.py -so - | sudo tee /usr/local/bin/gwhosts > /dev/null

sudo chmod 755 /usr/local/bin/gwhosts
