VPN

VPN Firewalling enables you to control the flow of data across Mako to Mako VPNs and Third 

Party VPNs.  Normally, once a VPN is created the traffic flows freely from network to network.  

If you want to restrict access to the VPN to specified computers or to a certain type of traffic, 

VPN Firewalling is the answer.

VPN Firewall

Control of the traffic uses a similar interface to inbound and outbound firewall controls.  First 

you must select your Mako to Mako VPN from the drop down list of Available VPNs.  Once 

you select which VPN you are wanting to Firewall, the screen changes to give you control as 

depicted below.  The method for adding rules is the same as for Inbound and Outbound 

except that the Default rule for VPN remains at the bottom to remind you the basic setup of 

the tunnel.
