Synology DSM does not provide a way for diagnostic tasks such as ping or traceroute, with an embedded SSH client these functions comes available. The GateOne SSH client offers other useful applications, such as bypassing a proxy, or if there is no VPN to the NAS and the firewall only allows port 443 (HTTPS) for the browser.

GateOne is not provided or managed by Synology itself, but can be retrieved from the SynoCommunity repository. The SynoCommunity offers free packages for Synology NAS devices.

Note. GateOne version 0.9.3 for DSM 5/6, support for DSM 7 is currently not available (23.8.2021).
