Set Synology NAS firewall

Help
1

Hello to everyone,
I have successfully installed and running VW (server installed 1.34.1 / Web 2025.5.0) on my Synology NAS. Everything works fine, but I want to fine tune the NAS firewall to restrict everything as the latest rule and at the same time allow VW to get all green (OK) checks on Diagnostics.

If I set on my firewall NAS the last rule as deny anything, then on VW Diagnostics the “Internet access” and the “DNS (github.com)” checks gives me error and I cannot sent email test from VW, but when I remove on my NAS this last firewall rule, then everything’s shows green (Ok).

Hope anyone can give me a hint to solve this!

This shows when NAS firewall last rule is deny anything:
