Description:

The tunnel feature is based on SSH tunnels and works in combination with Subutai Helpers and serves as an easy solution for bypassing NATs. In Subutai, tunnels are used to access the SS management server's web UI from the Hub, and open direct connection to containers, etc. There are two types of channels - local (default), which is created from destination address to host and global (-g flag), from destination to Subutai Helper node. Tunnels may also be set to be permanent (default) or temporary (ttl in seconds). The default destination port is 22.

Subutai tunnels have a continuous state checking mechanism which keeps opened tunnels alive and closes outdated tunnels to keep the system network connections clean. This mechanism may re-create a tunnel if it was dropped unintentionally (system reboot, network interruption, etc.), but newly created tunnels will have different "entrance" address.
