2.6.3 Concentrator

The VPN Concentrator provides an easy way for branch offices to connect to
headquarter through a VPN tunnel. All branch office traffic will be redirected to the
VPN tunnel to headquarter with the exception of LAN-side traffic. This way, all
branch offices can connect to each other through headquarter via the headquarter’s
firewall management. You can also configure BiGuard 50G to function as a VPN
Concentrator:

Please refer to appendix H for example settings.
