Glance Session Servers

To configure your 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.

  • 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 October 2019):
