Use RSW with VPN or remote desktop gateway

You can configure RSW for two different external access scenarios. One scenario is the installation of a VPN gateway and a VPN client on the external notebooks or PCs for access to the internal LAN. Alternatively, you can install a remote desktop gateway on a Windows Server and use this to establish RDP connections to the internal client PCs, as implemented in the SBS.

Use RSW with VPN

Use RSW with VPN

You need a firewall and a VPN gateway. You can do both e.g. with the open source software pfSense. This can be installed on a PC, such as IPU443 from NRG Systems GmbH. To achieve a good throughput, the CPU should support AES-NI crypto commands and use Intel Ethernet cards or chips.

After installation and configuration , you can set up OpenVPN.

You can then download the client software including configuration from the pfSense user interface.

Of course you can also use commercial products from Aruba, Cisco, ... Lancom to Zyxel.

Use RSW with Remote Desktop Gateway

Use RSW with Remote Desktop Gateway

If you want to use the remote desktop gateway, you must install it on a server (see below) and forward (NAT) the RDP port 3389 to the server on the firewall.

Create a Connection Authorization Policy in the remote desktop gateway manager. This policy specifies which groups are allowed to access this Remote Desktop Gateway. By default, RSW allows access to the RSWeb user group, see below.

Create a Resource Authorization Policy. This policy specifies which PCs are allowed access by which groups.
