Doesn't work with ENET Server in Docker Container

[bearrito]

I'm trying to use this so that I can tunnel an ENET service over TCP. https://github.com/lsalzman/enet

I'm building and running in a docker container.

My service runs with no issue while tcp2udp is not running, but when it is running I get an error, my error appears to originate from not being able to create a host/server. I'm guessing this is some sort of binding conflict. However, I've forced my server to use a completely different port than one below.

I've tried invoking tcp2udp in the following two ways.

/usr/local/bin/tcp2udp --threads=2 --tcp-listen 0.0.0.0:7446 --udp-bind=127.0.0.1 --udp-forward 127.0.0.1:6446 --tcp-recv-timeout=130 --nodelay

and

/usr/local/bin/tcp2udp --threads=2 --tcp-listen 0.0.0.0:7446 --udp-forward 127.0.0.1:6446  --nodelay

I do not have this issue on my local workstation.

Is there some sort of start-up or ordering condition of which to be aware? Namely, if I do not start tcp2udp allow my app to start, then exec inside the docker and run the above command, then I don't seem to have an issue.
