Today I have studied between VLAN and VPN at this sites or other external site
and I understand the VPN is secure connection through authentication check and through public internet network which is not secure. Most likely working VPN example, we remotely login our company network at home through VPN
The question, if company itself has apache server located inside the company for login page with authentication check , for example, connect SSL site at https://mycompany.com/localhost/login..php
, and then the empolyees will login into the company local network automatcially. If so , why we need so much third-party VPN software to do that in the past ?
For VMware company, actually I just know the company the solution to let your have Linux and Window system in the same computer and could be easily switched to each system on the same computer. How is related VMware software to VPN and VLAN? And what other service they provide so that they are ranked into large scale company like yahoo or Oracle company
What is the best example software tools to let others to know what this Vmware is doing for ?
