Can I use Glance solutions behind a firewall or HTTP proxy server? 
In most cases, yes. When you start a session, Glance attempts to connect to our servers using TCP/IP to destination port 5500. If it cannot connect to this port, Glance attempts to "tunnel" through the firewall via HTTP to destination port 80.  

Glance automatically chooses the best of several web browser technologies to help guests connect to sessions. Guests either connect to destination port 5500 or tunnel HTTP to destination port 80. 

We're constantly improving our ability to connect immediately and reliably. If you encounter a problem connecting, please let us know.
Can I use Glance solutions behind a Network Address Translation (NAT) router or firewall? 
Yes. Glance works reliably through most NAT routers/firewalls.
Can I use Glance solutions over a dial-up or satellite connection? 
Sure. But because dial-up and satellite data speeds are much slower than broadband, guests may not see a change to your screen for many seconds.
Can someone see my screen when I'm not using Glance Screen Share? 

No. For someone to see your screen, you must manually start a Glance session by clicking the "G" icon.

 

To view your PC screen, a person has to visit your Glance web page and know the Session Key, which changes with each new session.

Does Glance Screen Share allow inbound connections from the Internet? 
No. Glance software only makes outbound connections that you initiate by starting a session.
How can I configure my firewall to take full advantage of Glance performance?

Have your IT specialist add a rule that allows outbound TCP/IP connections to destination ports 5500 and 5501 and HTTP connections to destination ports 80 and 443 on Glance servers in the domain glance.net.

Alternatively, apply the rule to these address blocks (last updated 27 May 2016):

How can I get Glance Screen Share's new version with SSL encryption? 

Great news! Now you can SSL-encrypt Glance sessions. Session data between each participant and the Glance service gets sent using the strongest SSL encryption the person's computer or mobile device supports.

Set SSL-encryption 

Use the new No Key option -- now available in Glance 2.7 for Windows PCs (download here) and the Glance 2.8 for Macs (download here). 

 

Once installed, open its Settings... box and enable Encrypt my sessions (near the bottom of the list of Options).

How much bandwidth do Glance solutions use? 

Glance solutions use bandwidth only during a session. Traffic tends to burst up to hundreds of kilobits-per-second for several seconds whenever the screen being shown changes. As soon as the updates are sent, traffic returns back to near zero.

 

Most Glance sessions average about 50 to 80 kbit/s, comparable to active web surfing.

 

All traffic flows through the Glance servers.

When does Glance Screen Share create connections to the Glance service? 
Only during a session.
