GCP_firewall

Automatically generate GCP shell commands to set firewall that blocks ingress from certain region

1. Get the latest IP blacklist

Get the latest IP list here, and choose the output format as CIDR.

2. Build command generator

Note that this program requires C++17 standard, make sure your compiler is not too old

mkdir build && cd build
cmake .. -G Ninja
ninja

3. Run and generate commands

./command_generator -i (input ip list) -id (GCP project id)

4. Run the generated file in GCP cloud shell

chmod +x block_china.sh
./block_china.sh

Notes

If you are updating firewall rules, make sure clear the old ones before adding the latest rules.
