I have experience in Amazon AWS deploying EC2 instances and VPN access, configuring a VPC, etc. Now, I'm deploying a private cloud using a small XenServer host. It's working on my private network, and is doing really good.
Well, I need to put the server on the public network, but I'm on a budget, and can't invest on a firewall or other external security device to protect it. So, right now, things are like this:
Internet <---> Router <---> XenServer host
I will appreciate some direction about what I should research to reach these goals:
- Protect the XenServer host (for example, is it possible to enable
ufwor something like that? Where?)
- Give it VPN access to the VM guests (I think it will be similar to AWS -- configure a gateway to Internet, configure a VM with a VPN server, etc.)
