## Usage

- Must be executed with `NET_ADMIN` capabilities.

- Configuration is defined by an environment variable (`REROUTER`) which contains: `::`. Multiple routes could be configured separated by `,` character.

For example, if you would like to reroute port `1022` to port `22` in host `192.168.200.4` run:

```bash

docker run \

    -d \

    --cap-add=NET_ADMIN \

    -p 1022-1024:1022-1024/tcp \

    -e REROUTER="1022:192.168.200.4:22, 1023:1.2.3.4:5432, 1024:10.50.0.4:80" \

    --name=net-rerouter \

    manuellr/net-rerouter

```
