Traffic balancing daemon for VyOS Router

We have two uplink providers with different NAT subnets for each.

The daemon regularly checks the usage of each uplink interface and moves firewall NAT rules from the more loaded to the less.

Test

go test -v ./cmd/vyosctl
gosec -exclude=G402 ./...

Build

go mod download && go build -o vyosctl ./cmd/vyosctl

Flags

-c <config file path> - path to *.toml config file

Config
