Need to add to this: |

Option #2 has a few downsides: |
60 |
1) The system running the VPN-server will have a lot more bandwidth |
61 |
utilisation. (Backups for other systems will go through the link this one |
62 |
has) |
63 |
2) If that system is down, none of the other systems can be accessed via VPN. |
64 |
|
65 |
For me the downsides don't count as the server can be accessed really |
66 |
easily and I pay the same for my home internet connection when I use it or |
67 |
don't use it. |
