How to completely disable internet access for WorkSpace and Docs?

[dwpoint]

Hello. I installed the excellent OnlyOffice SpaceWork program on a local Windows 2016 x86 server. Also before that I installed OnlyOffice Docs.

Tell me, is it possible to somehow completely disable Internet access for all OnlyOffice components? I would very much like OnlyOffice not to collect any information and it is especially important that the documents do not end up on the network.

I tried to disable in the firewall:

1. ONLYOFFICE DocumentServer Proxy Service
2. ONLYOFFICE Jabber
3. ONLYOFFICE Mail

But when registering in WorkSpace, I still received an e-mail to confirm my account.

I would like to block internet access so that WorkSpace can't even send emails.

Is it possible?

That is, I would like to completely disable the possibility of any OnlyOffice connection to the Internet, both for OnlyOffice Docs and OnlyOffice WorkSpace.

Hello @dwpoint. By default, Onlyoffice Workspace uses notify.onlyoffice.info as the smtp server. If you disable your internet connection, you should set up a local smtp server for notifications.

Onlyoffice Workspace includes Onlyoffice Docs and you don't need to install it again before or after installing the workspace.

@Carazyda It's just that for my task I don't need access to the Internet at all. Do you understand? My task is only to co-edit the document. I want to allow access to the workspace to everyone who is on the local network.

I don't want to use smtp at all, you know? And I don't want to use the mail itself either. She is not needed.

Tell me, can I somehow disable Internet access for WorkSpace? So that no updates come, no notifications, etc. Do you understand what I mean?

In this case, just turn off the Internet on the server where Onlyoffice is installed.

@Carazyda Unfortunately, I can't do that because other programs need to work with the internet. For example, parsing through Python

If you need to block access to the Internet only for certain programs, you can set up rules in Windows Defender Firewall. List of ports used by Onlyoffice Docs and Onlyoffice Groups.

@Carazyda And how to find out what ports are used by these programs to block them?

[Carazyda]

I have attached links to our help center with a list of ports in the comment above.

@Carazyda Thank you. And tell me, if I block these ports, will WorkSpace be available through the browser as a local website?

[Carazyda]

Yes, if you block them for internet traffic only.
