wenn´s Geld kosten darf (ich weiß, wie ketzerisch):
bummelig 12,- im Monat, managed Service, auf "Host-PC" läuft Soft, die sich in regelmäßigen Abständen bei einer Farm meldet.
Client ruft Browser auf, connected auf eine Seite der Farm, Farm stellt als Mittler die Verbindung zum Host-PC her.
hier ein paar details:
|Q: How does GoToMyPC Corporate work through my firewall?|
A: GoToMyPC Corporate adjusts itself to your firewall, so you generally do not need to change or open ports in your organization’s firewall. GoToMyPC Corporate does not open any new ports that an intruder could exploit, or open any new firewall holes. All connections are made by using outgoing TCP ports that are often left open for Web browsing (ports 80, 443 and/or 8200). Unlike other remote-access products, GoToMyPC Corporate does not accept incoming connections that could allow intrusions. GoToMyPC Corporate encapsulates all traffic inside standard HTTP wrappers, ensuring compatibility with firewalls that inspect payload.
Q: Will GoToMyPC Corporate work with a Network Address Translation (NAT) device?
A: Yes. Because GoToMyPC Corporate uses outgoing HTTP requests, it is compatible with the dynamic IP addresses generated by network and port address translation (NAT/PAT) devices that block incoming sessions.
Q: Which port numbers does GoToMyPC Corporate use, and can I change the port numbers?
A: GoToMyPC Corporate uses one of the several ports that are typically left open so that users can access the Internet (port 80 or 443). This means that you generally do not need to configure firewalls to allow GoToMyPC Corporate connections. If your organization uses a proxy that restricts traffic through port 80 or 443, you may open port 8200 for GoToMyPC Corporate connections. Citrix Online provides a Connectivity Test Wizard that you may use to optimize your GoToMyPC Corporate connection ports.
Q: Does GoToMyPC Corporate require a static IP address?
A: No. Unlike other remote-control and remote-access products, the GoToMyPC Corporate protocol design is compatible with dynamic and static IP addresses. GoToMyPC Corporate automatically detects the IP address, so your users do not need to configure any software settings.
übrigens mit vernünftiger performance, kein VNC-Müll
