Are there any special things to consider when trying to access a traditional client/server application using a VPN connection?
We are currently experiencing an incredible delay in accessing the application using a VPN connection. Probably something is incorrectly configured, I don't have any specifics on what VPN (hardware/software) is being used, assume it's hardware based, vendor is Juniper Networks. Hardware and networking is outsourced, so always hard to discuss performance problems...
Probably a bandwidth problem.
I don't have any significant delays with other applications. If it was a bandwidth problem I suppose there would be a general problem? Or is the required capacity for Progress client/server applications much higher than for Outlook, Windows Explorer, DB Navigator in OEArchitect (preview data), Toad for Oracle...
Are you running a fat client over a VPN? Or is the local client talking to an appserver?
Combined application but the majority is fat client...
No plans (aka budget) to tailor it to a slim fit.

Then it's probably a bandwidth issue, particularly if the application is running queries on large datasets which require calling the client to resolve.
If the application be run on a local (to the database or database network) machine and then do a remote-desktop over the VPN, that would help a lot as it would get rid of all the db/client network traffic having to be shipped across the VPN.
Like Tim said maybe you can use a terminal server? Then 25 Kbps per session would suffice. If it is ADM1 like fat client/server then you have no other option. You need at least 10 Mbps to get things going...
Thanks. So the minimum bandwidth capacity when using a fat client is 10Mbps.
I'll ask if it's possible to set up a Citrix or sortlike environment.
