SOLVED.
From Akka:
eqemu_config
Make sure localaddress and address are set properly. address typically being your public address and localaddress being your LAN address.
If you are pure LAN, just set both to your LAN.
Kovi:
I don't remember ever having to use my public ip using the linux installer. what's the difference with akk-stack?
Akka:
Because Docker containers are in their own network (LAN)
And the server needs to send your client the address that it can network to, not the one implied inside the docker container
So if your PC is on 192.168.65.2 and your server is on 192.168.65.3 but really your docker container server is 172.16.0.2 but is 1:1 NAT'ed to 192.168.65.3 you still need to send the client 192.168.65.3
Your client won't know how to get to 172.16.0.2 if you just let the container imply what its to network on
SOLUTION for local server:
set "address" and "localaddress" to 192.168.65.3 (server LAN ip)
