If you have clients outside your firewall connecting to any telnet server or Host On-Demand Redirector inside your firewall, you should configure TLS and SSL connections to ensure your data is secure. To configure TLS and SSL for servers and clients:

1. Obtain or create certificates for servers
2. Make server certificates available to clients
3. Configure clients to use client authentication
4. Obtain or create certificates for clients needing to provide client authentication.
