I am looking for esxii offline because I have no internet connection.
My questions are: Is esxi offline the same as online?
If one day I would like to buy a virtual router vROUTER from QNAP or CISCO SYSTEM cloud etc... can I get internet from there? Or do I have to buy Esxi online for it to work at all?
I would like to get some clarification on this.
Thank you and I look forward to your reply.
What do you mean by "ESXi offline" and "online"?
If you're asking if you must connect an ESXi host to a network which has internet access, then no you don't, unless you want to manage it over the internet.
Whether the VMs you build on that ESXi host need internet access or not is a whole other matter.
The Offline Bundle is an optional download, which one can use to e.g. manually update/patch an ESXi host, or to create customized installation images. This bundle has basically nothing to do with VMs.
From a networking perspective, ESXi can be used - regardless of the license - like any other system.
