My mail to this address bounced:

I'm interested in trying out bursting to GCP from our Slurm cluster. 
However, one of the listed prerequisites is a site-to-site VPN gateway:

Though this may seem trivial to some, it can easily be a showstopper to 
newcomers like myself!  The above page doesn't contain any links 
whatsoever to pages explaining the prerequisites

Googling a bit myself, I found this page:
Disappointingly, only a list of hardware VPN solutions are listed, plus 
StrongSwan running on Debian.

We run CentOS 7 and 8 servers, and RHEL/CentOS includes the LibreSwan 
VPN software.  I would prefer to use LibreSwan then, but how do we 
connect to GCP??

Again, some googling showed this page:
This page states:
 > It turns out getting libreswan to play nicely with Google Cloud VPN 
(Classic) is much harder than it needs to be. There are various Medium 
and mailing list posts about this, but none of the solutions actually 
survive a rekey. So here's what works.

In conclusion, how about you guys setting up links to relevant 
instructions regarding VPN and the other prerequisites?
