Overview

This page lists the available connection types for each protocol category and provides guidance on when to use each one.

Use this reference when configuring the Provider & Protocol section of an application.

The main settings are:

Provider - for example Local, AWS, etc.
Protocol Category - for example, HTTPS, Server, etc.
Protocol Type - for example, RDP, SSH

After selecting a Protocol type, additional fields may appear depending on the protocol. These can include port settings, protocol-specific parameters, or security options.

Connection Types by Protocol Category

Protocol Category	Protocol Type	When to Use
Web Applications	HTTP	Use for web applications that do not require encryption
	HTTPS	Use for secure web applications (default port 443)
	SaaS	Use for external SaaS applications managed outside your environment
	Link	Use for simple redirects to external URLs without a backend connection
Networks	TCP	Use for access to a specific TCP port or service
	Network	Use for access to multiple ports or broader network ranges
	Desktop App	Use for applications that require a local client
	SSH Tunnel	Use for secure tunneling of traffic over SSH
	HTTP Tunnel	Use for tunneling HTTP traffic through Cyolo
Servers	RDP*	Use for remote desktop access to Windows servers (default port 3389)
	SSH	Use for command-line access to Linux or Unix systems (default port 22)
	VNC*	Use for remote desktop access using VNC
	TELNET	Use for legacy terminal access (not secure)
Databases	PostgreSQL	Use for access to PostgreSQL databases
	MySQL*	Use for access to MySQL databases
Files	SMB	Use for access to file shares using SMB

Protocol Category Descriptions

Web Applications

Use this category to publish web-based applications, including internal services, secure applications, SaaS platforms, and external links.

Networks

Use this category for network-level connectivity, including direct port access, broader network access, and tunneling scenarios.

Servers

Use this category to provide access to servers using remote desktop or terminal-based protocols.

Databases

Use this category to configure access to database services.

Files

Use this category to provide access to file shares.

Note on Ports

Default ports are automatically suggested for common protocols, such as:

HTTPS: 443
RDP: 3389
SSH: 22

Notes per Connection Type

RDP

Ensure the server has the Remote Desktop Services (RDS) role added and RemoteApp programs published.

VNC

Ensure the server has the Remote Desktop Services (RDS) role added and RemoteApp programs published.

MySQL

MySQL Client/Server Support

Cyolo supports the following MySQL client/server apps:

Client: v8.1+, v9.0.1/9.1
Server: v5.X, v8

📘
Note
Client v9.x cannot work with server v5 (this is not related to Cyolo).
