You are deploying a virtual private network (VPN) for remote users. You want to meet the following goals:
- The VPN gateway should require the use of Internet Protocol Security (IPSec).
- All remote users must use IPSec to connect to the VPN gateway.
- No internal hosts should use IPSec.
Which IPSec mode should you use?
- You should deploy host-to-gateway IPSec mode. In this configuration, the VPN gateway requires the use of IPSec for all remote clients. The remote clients use IPSec to connect to the VPN gateway. Any communication between the VPN gateway and the internet hosts on behalf of the remote clients does not use IPSec. Only the traffic over the Internet uses IPSec.
In host-to-host IPSec mode, each host must deploy IPSec. This mode would require that any internal hosts that communicate with the VPN clients would need to deploy IPSec.
In gateway-to-gateway IPSec mode, the gateways at each end of the connection provide IPSec functionality. The individual hosts do not. For this reason, the VPN is transparent to the users. This deployment best works when a branch office or partner company needs access to your network.
