Figure 95 Simplified network topology after IPsec tunnels are established
When setting up a system as described above, the user must be careful to select an IP addressing scheme so that the IP
addressing range of one linked network does not overlap the IP address range of another linked network. Each network
must have a unique IP address range.
3. ADVANTAGES OF USING IPSEC
Using IPsec with the Fusion router provides several key advantages.
Eliminates the need to have static IP addresses associated with Fusion cellular accounts. After an IPsec tunnel is
established, devices from either the corporate network or the remote network can initiate communications.
One or many devices can be connected to a Fusion router. Each device will have complete access to and from the
corporate network without complicated routing or port-forwarding rules.
IP Persistence: An application running on the corporate network can reach any Fusion router or remote device
connected to the Fusion LAN using its private IP address regardless of which WAN interface is currently active on
the Fusion.
IPsec provides enhanced security, protecting critical data as it travels through public networks.
