Synology has no access to internet (e.g. system update or CloudStation)

Good Morning, Evening or Afternoon

I'm playing around with UTM9 for about a week now but I didn't figure out how to allow my synology diskstation to access the internet. I wanted to allow: the system to check for updates and download them, the package manager to do the same, the CloudStation to sync with DropBox, google drive, onedrive, and pyLoad to download files.

I thought it would be enough the create the following DNAT-rule:

  • For traffic from: Any
  • Using service: 
    • type: TCP
    • destination port: 5000,5001,6690
    • source port: 1:65535
  • going to: WAN (Address)
  • Change the destination to: synology(host), specified with static IPv4 and MAC address
  • Automatic firewall rule: check

What am I missing that it doesn't work?

Furthermore: pyLoad itself is ultra slow - not the downloadspeed (as I am not yet able to test this) - but just switching tabs withing pyLoad takes ages. What could be the reason for this behaviour? It's not that slow if access without the utm.

Thank you very much in advance for every advice.

  • Hi, Kalle, and welcome to the UTM Community!

    Your second question could be the MTU problem.  Is that set at 576 on the External interface?

    Does doing #1 in Rulz clarify anything?

    Cheers - Bob

  • Thank you Bob for your kind reply.

    IPS / Flood Protection / file related patterns are all deactivated atm.

    The MTU was set to 1500. Setting it to 576 didn't help. What is the reason for setting it to such a low size?

  • Sorry that my comment was confusing, Kalle - 1500 is correct.  People were having problems because some ISPs were sending an instruction to use 576.  That happened in North America and Europe.

    Even though you say that you have all of those things deactivated, you still should confirm that the relevant log files are empty.

    Cheers - Bob
