WTSGateway
by Terminalsoft

  WTSGateway When installed on any Windows 2000 or XP machine, WTSGateway act as a gateway for both RDP and citrix ICA protocols. This means you do not need to expose your whole network to the outside.Your firewall will only need to be opened to allow external users to communicate with the WTSGateway machine. On this machine you will add the IP addresses of all your Terminal Servers and WTSGateway will balance the load among the servers, establishing the connection directly between the WTSGateway and the Terminal Servers. Therefore from the outside, the only machine visible is the WTSGateway one.
It can be configured to listen on any port you want (443 for example) and to connect to your Terminal Servers listening on any port (like 1494, 3389, 3390 and so on). A must have if you do want a secure TS environment.
