Strange outgoing connections from Synology


Question

Hi, I've noticed using my router that sometimes there is some strange outgoing connections from my Synology to external IPs.

 

It is definitely not open incoming, no ports are forwarded to it, so these are outgoing connections to external IPs destination port 23949 which is strange because its an unassigned port.

 

These IPs according to ipinfo are mobile network ranges so that also seems strange to me.

 

How can I tell what process is establishing these connections on Synology?

 

I blocked one on my router a week or so ago and now there is another its connected to!

 

Thanks

Not much, i think its plex although can't be sure. If it was windows i would run current ports app to easily see what process is making the connection. Why isnt there something similar in linux?

 

Yes I have uPnP disabled on my router.
