Application Gateway doesn't support email protocols such as SMTP, IMAP, and POP3. An application gateway supports only one public IP address. Keep-Alive timeout governs how long the Application Gateway will wait for a client to send another HTTP request on a persistent connection before reusing it or closing it. Deployment model considerations. These ports are protected (locked down) by certificate authentication. The connector service redirects to the Load Balanced resource. Application Gateway v2 does not currently support IPv6. Because Application Gateway can now also authenticate the client, it becomes mutual authentication where Application Gateway and the client are mutually authenticating each other. Application Gateway can also communicate with instances outside of the subscription it's in. Privacy policy.
