What have you done so far to eliminate that as the cause? Given the [fundamental nature of the feature in question|http://guacamole.apache.org/faq/#probably-not-a-bug] and the uniqueness of what you're doing here, some unexpected behavior of that "Docker -> socat -> Docker" portion seems more likely.

If Guacamole is running beneath Docker on the same machine as TigerVNC, I'm not sure what you're trying to avoid exposing. Any Docker container on that machine will be able to connect to your TigerVNC using the IP address of the Docker interface.

> Guacamole is disconnecting me from my VNC server after a few seconds of connection. I get fine streaming, but then the connection suddenly disappears. Logs don't show much: [https://gist.github.com/kenzierocks/0e1f86d3850497f5f7438709b0811641|https://gist.github.com/kenzierocks/0e1f86d3850497f5f7438709b0811641.]. I am streaming this in a bit of weird setup, but I don't think it should cause any issues. Basically I host TigerVNC on my machine, then Guacamole runs in a Docker container, and to avoid exposing the port I pipe the VNC data through socat in another docker container. This means the flow of data is VNC -> Docker networking -> socat -> Docker networking -> guacd, but I don't think this should result in random disconnects. socat reports that the sockets are reaching EOF.
