My company has a server in a colocation center. It runs all of our stuff. I have a couple machines that are throughout the world who need to join that domain.
We are using LogMeIn Hamachi as our VPN. We're a startup, don't have a lot of funding and would like to avoid spending lots of $$$.
Do we have to purchase a VPN appliance, such as a SonicWall or Cisco box?
I thought about a software vpn such as Forefront. But Forefront wanted 4GB of ram--and our main server has 6. Maybe it would be possible to setup an open source software vpn as a virtual machine perhaps (we have and use Hyper-V a lot).
