Caching servers and VPN

We have caching servers set up in all of our offices, and this brought some great efficiencies to project team members that sit in the same office.  However, due to the current situation gripping the world, 100% of our users are working away from the office, so no two users are on the same LAN.  Our VPN is currently routed through one of 4 different offices throughout the country - depending, theoretically, on which one is closest to the user.  As such, all our ProjectWise users are connecting to one of these caching servers through the VPN.  This could theoretically put the project files "closer" to the user, though obviously the user now has to go through the VPN to download these files.  My question is, should we be doing this, or should we be sending these users directly to our Bentley-hosted cloud data source?  My sense is that we should not be using the caching servers and VPN and instead going directly to the Bentley-hosted cloud server, but that is just a guess.  Can anybody here offer some advice that is perhaps better informed than my "gut"?  Thanks.

  • Hi Jon,

    Our users are still using VPN to access on-premise PW Integration servers and then for accessing external datsources/Bentley hosted the users are still looking at our internal Gateway/Cache server.

    I have however adding some additional routing so if it recognizes the users are connected via the VPN we tell the users machines to go directly to the hosted servers using their internet connection rather than through the internal Gateway/Cache server.  With this solution we still retain control of what datasources the users see and can centrally distribute the datasource and routing information rather than amend all the users network configuration settings.

    So in our DMSKRNL file on the gateway/cache file it does the following.

    1) Are the users on a office subnet if so point them to their local office cache server and then either out via the Cache/Gateway server or local office internet break out.  If not go to the next step.

    2) Are the users using the VPN (certain subnet) if so tell the users machine to go directly to the external/Bentley hosted server.  If not go to the next step.

    3) None of the above apply so allow user to go out via the Cache/Gateway server (Usually this means office does not have a local cache server).
