DNAT TCP 6690 Synlogy Cloudstation

Hi, and welcome to the UTM Community!

Your DNAT rule should look something like:

DNAT : Internet -> cloudstation -> External (WAN) (Address) : to DS01

See #4 in Rulz to understand why I say that.  If you already have such a rule and the DNAT you showed us is for internal accesses, see Accessing Internal or DMZ Webserver from Internal Network for the solution to a parallel problem.

If you're still having blocked packets in the firewall log: Alone among the logs, the Firewall Live Log presents abbreviated information in a format easier to read quickly.  Usually, you can't troubleshoot without looking at the corresponding line from the full Firewall log file.  Please post one line corresponding to those above.

Cheers - Bob

No packets are being blocked, so your solution is in Accessing Internal or DMZ Webserver from Internal Network.

Dear Bob,

Thanks for the solution, it works :-)

This the final DNAT rule with additional FQDN and local nas name:
