Providing remote access for users direct to their PC is as simple as setting a fixed IP address for that PC then opening a firewall port (specifically for that user) and they can logon.
However scaling this solution up does present some challenges the first challenge is that the router will only support a certain number of port redirections and one has to be set up for each PC that needs to be accessed remotely In addition it becomes quite cumbersome to manage the fixed IP addresses for all the PC's and confirm that the right user has the right port number, record all that information and make sure that that information gets passed onto the user.
I've been looking for a better solution for this for some time Microsoft offer a product called remote desktop gateway which is very complicated in cumbersome to manage an I have been looking for a solution which provides the same functionality but is a lot less complex and onerous to manage plus be cost effective.
Today I have evaluated TSX gateway by thinstuff.com I have been aware of these guys for several years but haven't had a specific requirement to use any of their products.
The way that this product works is you install it in one location on your network, on an existing server and then all of the users connect from outside the network to that one [gateway] server, authenticate to that server and then connect to their own PC based only on the PC name. this means that no specific port number and no set of remote desktop icons is required. Also if user needs to use another PC or gets a new one it's just as simple as them using the other PC name that they would like to connect to and so long as I have given them access to that PC they can connect without further requirement for support or interaction with me.
There are another couple of benefits to this product as well:
The free included certificate which the gateway software creates itself. This needs to be manually (but easily) installed on each PC that will connect remotely.
Or, alternatively you can purchase a public certificate for about $50 per year which means that any PC on the Internet (for example staff home PCs) can connect to your remote desktop PCs so long as they have the password without any setup requirement.
The software is US $259.00 for unlimited connections and can install on one of your existing servers.
