A zero-dep port forwarder.
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.
bash
routez 127.0.0.1:1234 127.0.0.1:4321
Create a config file with source:port destination:port (exactly 1 space):
127.0.0.1:1234 192.168.0.33:22
127.0.0.1:4321 192.168.0.33:22
Now run with:
bash
routez routez.config
To output color logs, have a look at pipeview.
Either run:
bash
routez 127.0.0.1:1234 127.0.0.1:4321 | 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:
bash
routez 127.0.0.1:1234 127.0.0.1:4321 | pipeview
