I’ve got a Synology NAS. Setting the connector up on the NAS I was able to access resources on my network, but not from the NAS itself (things I tried to access: DSM, Plex, Drive). But when I deployed the connector on a separate device (a raspberry pi), I was able to access the device itself apart from being able to access any of the resources on the NAS. I would prefer having the connector run on the NAS, instead of it running on a separate device.
FYI: I deployed the connector on Synology using the Docker instructions.
