Hi @bperezgo, @PhilipDAth, @alemabrahao, @BlakeRichardson Thanks everyone for your input and suggestions. Unfortunately, I’ve applied all the recommended measures, including: Layer 3 firewall rule blocking traffic to 239.255.102.18; Layer 7 firewall rule denying hostname anydesk.com; Adding all known AnyDesk domains to the Content Filtering blocked URL list (e.g., *.anydesk.com, *.net.anydesk.com, *.relay.anydesk.com, etc.). I've also waited over 10 minutes and restarted the client device to ensure a new flow was created. Despite all of that, AnyDesk is still working normally on the network. If anyone has additional ideas or a more advanced workaround, maybe involving DPI or other techniques. I’d really appreciate your help. Thanks again, Gabriel
