50GB used due to misconfiguration?

I deployed a Starlink roam  on the 50GB plan the past weekend and consumed all 50gb in ~3 days.    I have a Synology router attached to one of the two extra ethernet ports on the Starling Gen3 router and placed the Gen3 router in bypass mode.  This worked great!

We were moving very large video files within the local network to a NAS attached to the Synology, and generally only had a few phones and one or two laptops connected the network creating outbound or inbound traffic via the starlink.  So I was surprised that the 50GB was consumed so quickly.  

Is it possible that I have misconfigured the Gen3 router or the Synology router such that Starling is metering internal traffic?  I'm used to typical networks that local traffic remains local which should be happening in this environment too, but curious if I'm overlooking something.

 

TIA

Starlink data consumption is only calculated by incoming and outgoing of the Starlink terminal. 
 

I’d assume something on your nas is linked remotely..

 

or the sync, was done across internet rather than local… 

 

also I’d connect the Starlink router and monitor incoming and outgoing bandwidth… no bypass mode. 
 

Ensure all networked clients are on the Starlink wifi and not going back over the internet to connect to the nas.

Thanks.  The NAS has no internet syncing configured, and is not exposed to the internet for remote access.  I do however need to use the DNS zone on the Synology router so various clients can get to the NAS easily.  I don't believe the Gen3 Starlink router will perform this service.

When the Starlink is in bypass mode, is its wifi turned off?  We used the same SSID/pw on the starlink router (before set to bypass mode) when configuring the Synology router.  We did this to ease client transition.  If the Gen3 wifi is still on, I can change the SSID/pw so no one will join there when the Synology is providing wifi.
