routez

A zero-dep port forwarder. Routez supports both TCP and UDP.

Why?

Originally implemented to reroute traffic from Class-C IPs (192.168.x.x) to Docker Class-B ones (172.18.x.x).

Useful when creating an IPVLAN (L3) which has the Class-B IPs and when one wants to reach them from Class-C ones.

Example usage

routez 127.0.0.1:1234 127.0.0.1:4321 TCP

Example usage - config file

Create a config file with source:port destination:port (exactly 1 space):

127.0.0.1:1234 192.168.0.33:22 TCP
127.0.0.1:4321 127.0.0.1:7890 UDP

Now run with:

routez routez.config

Pipeview

To output color logs, have a look at pipeview.

Either run:

routez 127.0.0.1:1234 127.0.0.1:4321 TCP | pipeview '(.*?) (.*?) (.*?) (.*?) -> (.*)' 'blue cyan white green bred'

Or create a pipeview.toml file in the directory you are calling routez from (see example in this repo) and invoke:

routez 127.0.0.1:1234 127.0.0.1:4321 UDP | pipeview
