update cache Server/message relay

Question

Hi all, 
 Anyone can help me to check my concern about my deployment scenarios with Sophos Central server base deployment? 
 1. Corp Branch has an internet 
 2. OT Branch without Internet and have many workstations 
 3. The workstation of the OT branch is directly connected to the OT Server alone. 
 4. OT Server connected to Corp branch via update cache/message relay. 
 If possible that the OT branch Server can make a cache Server/message relay without the internet? 
 One can help with this? 
 
 Thanks, 
 Ted

Hi Teodolo, 
 Thanks for reaching out to the Sophos Community Forum. 
 In this setup, the OT Server will update the protection components to protect the system but the Update Cache/Message Relay components aren&rsquo;t able to update. An Update Cache/Message Relay requires a connection to Sophos Central directly to update.
