Glance Session Servers
To configure your firewall to take full advantage of Glance performance, have your IT specialist add a rule that allows:
-
Outbound TLS connections to destination port 5501.
-
HTTPS and WSS connections to destination port 443 on Glance servers in the domain
glance.net.
Alternatively, apply the rule to these address blocks (last updated April 2021):
