Hi

I have setup VPN connection across four office.
Each office have DrayTek 2830 router.

VPN between offices is working fine.
But VPN connection is very slow. When I access any computer over VPN at other offices.
I test internet speed, Download speed is 15mbs and upload speed 1.15mbs.

How can I improve connection speed, so that I can services of all the offices accross network.

Please can some advice and put me in the right direction.

Many thanks

Hi - could you just clarify which bit is the slow bit? You say that the Office to Office VPN is working fine - do you mean that it connects but is slow or is it a different connection that is slow? What bandwidth (upload & download) Internet connections do you have at each office - is this the 15/1.5mbps that you mention? Is there a dedicated VPN from each router to every other or is it a hub and spoke configuration with everything passing via a central "head office"? Your Internet connection speeds look pretty much standard for ADSL+, what are they when going via the VPN?
