![]() ![]() When set to ‘Full (Strict)’, traffic from Cloudflare to the origin will also be encrypted with strict validation of the origin certificate. ‘Full’ specifies that traffic from Cloudflare to the origin will also be encrypted but without certificate validation. Traffic will be sent over an encrypted connection from the client to Cloudflare, but not from Cloudflare to the origin. ‘Flexible’ enables termination of the client connection at the edge, but does not enable TLS from Cloudflare to your origin. Spectrum offers three modes of TLS termination: ‘Flexible’, ‘Full’, and ‘Full (Strict)’. The Edge TLS Termination toggle applies only to TCP applications. If you enable Edge TLS Termination for a Spectrum application, Cloudflare will encrypt traffic for the application at the Edge. ![]() Spectrum will also only respect rules created with the actions allow or block. Cloudflare only respects rules created for specific IP addresses, IP blocks, countries, or ASNs for Spectrum applications. If IP Access rules are enabled for a Spectrum application, Cloudflare will respect the IP Access rules created under Security > WAF > Tools for that domain. The number of ports in an origin port range must match the number of ports specified in the protocol field.Ĭonnections to a port within a port range at the edge will be proxied to the equivalent port offset in the origin range.įor example, in the configurations above, a connection to :1005 would be proxied to port 3005 on the origin. Spectrum applications can be configured to proxy traffic on ranges of ports. PortsĬloudflare supports all TCP ports. Messages from your server may be rejected if an MX record for your domain is associated with a Spectrum application, as the IP address of server will not match the Spectrum IP address. Spectrum applications do not have reverse DNS entries.Īdditionally, SMTP servers may perform a DNS lookup to find the MX records for a domain.
