Overview of the Planning Process

The areas that require planning when using a VPN firewall that has dual WAN ports include:
• Inbound traffic (for example, port forwarding, port triggering, DMZ port)
• Virtual private networks (VPNs)
The two WAN ports can be configured on a mutually-exclusive basis to either:
• Rollover for increased reliability, or
• Balance the load for outgoing traffic.
These two categories of considerations interact to make the planning process more challenging.

Inbound Traffic

Unrequested incoming traffic can be directed to a PC on your LAN rather than being discarded.
The mechanism for making the IP address public depends on whether the dual WAN ports are
configured to either roll over or balance the loads.
