Integration of 3.3 with 5.18 is not possible IMO.
Also ver 3.30 UM have the bug of simultaneous usage of ppp users , means single ID can be used at multiple computers simultaneously.It was corrected after 4.17 version.
This option does not make a new connection; instead it allows testing for the presence of an existing connection that can be shared. (See section 4.17.5 for more information about SSH connection sharing.)
