SSH Gateway

Overview

SSH Gateway is used to accelerate access to overseas assets without installing additional programs. It relies on SSH port forwarding of a jump host.

How it works

1. Next Terminal actively connects to a jump host (SSH Server)
2. Select this SSH gateway when creating assets
3. Traffic is forwarded through SSH port forwarding on the jump host

Typical scenarios

• Accelerate access to overseas servers
• Improve cross-region connection performance

Usage

1. Add SSH gateway

In SSH Gateway management, configure jump host info:

• Name: for example Overseas Jump Host
• Address: jump host IP or domain
• Port: SSH port (default 22)
• Username: SSH account
• Password or key: authentication credential

2. Add asset and bind gateway

When adding overseas assets:

• Fill target asset IP/domain
• Select jump host in SSH Gateway dropdown
• Fill other connection settings

3. Access asset

Traffic is routed through SSH gateway and connection speed is improved.

Example

Suppose direct access from China to us-server.example.com is slow. You can use jump host us-jump.example.com:

1. Add SSH gateway with address us-jump.example.com
2. Add asset us-server.example.com and select this gateway
3. Access traffic is relayed through the US jump host

Notes

• Ensure SSH Server allows port forwarding (AllowTcpForwarding in sshd_config)
• Ensure jump host has good connectivity to target assets
