We have a DS3 connection to the internet. And two of our sites connect over VPN. A simple connectivity diagram to represent it is as follows:
Desktop---VPN-Router1----Internet Router1 --------------------- Internet Router2 ------- VPN Router2--- Sun Server
VPN over DS3
I can download files to the desktop from the server at 800Kbps + but can upload at less than 50 Kbps. I am using secure copy (WinSCP at desktop and openSSL on the server)
Any clues where I could start looking for issues
We dont have any rate limiting. Queueing is FIFO.
