Hi,
I think you did not do the step "install software". In SlapOS, you can
request N instances of a given software. This way, you can run for
example 10 independent instances of ERP5 (one for devt, one for prod,
one for friend). And to create a SaaS service, it reduces costs a lot
(it is possible to run 100 to 200 ERP5 instances on a cheap server).
But first, you must say to your server "I want ERP5 to be installed on
this machine".

Should be fine. If you see many IPv6 addresses on the bridge, then OK.

Perfect.

I do not understand.

You can read this:
http://www.slapos.org/wiki/osoe-Lecture.SlapOS.Extended/developer-Introducing.SlapOS.Architecture
It explains. Each instance has:
- one local IPv4 address so that any IPv4 software can be used
- one global IPv6 address, to interconnect all services between
different hosts
- and use stunnel to forward IPv6 to IPv4 (so that two IPv6 incompatible
services can connect eachother through IPv6 in a secure way)
Tomorrow, I will setup an instance for you on some machine.
Regards,
JPS.
