I need some help with RDP.
Little explanation first...
The company is divided into two offices:
- the first, which houses server room. Uses 1M/0.5M xDSL as an internet connection and Win2008R2, which runs database and ERP application.
- the second, from which users connect to the main office (via another xDSL, this time 1M/0.25M). Up to 8 users will connect simultaneously via Remote Desktop.
Both "branches" are connected via IPSec VPN. Both routers are Linksys BEFVP41, which means I don't have much configuration options to work on.
I've set up "QoS" (yeah, in quotation mark as you can't call it QoS) - default RDP port has the highest priority. My routers have similar options to this one:
My friend told me that even if I used policy based QoS, DSCP will be removed by my ISP (I'm new to QoS) and it won't work.
My users complain that the connection is slow and unreliable (RDP sessions tend to "freeze").
At first I've tried to use private IP to connect to the server via IPSec. It seems this type of connection is bit slower than using public IP address.
Of course, I've disabled all the graphical fireworks, disabled autotuning like in this tip:
Is there anything I can do aside from investing in a connection with bigger upload on the server side?
Let's assume for this discussion that users from the main office aren't uploading anything and there packet loss doesn't occur (as I haven't notice any abnormal losses).
I think I have posted all the important facts. If not - please ask and I'll answer...
