Proxy & Firewall Settings

Firewalls, filtering, caching, etc.

Libraries and districts using firewalls, proxy servers, caching servers, filtering software and other security features may need to open certain ports and safelist certain domains to provide network users full access (incoming and outgoing traffic) to avoid caching errors or impeding access to KYVL resources. Consult the documentation for your specific service or device for implementation instructions.
