5. Firewall, Failover and OOB Access • Navigate to the System: Firewall page, then click on the Forwarding & Masquerading tab. • Find the Source Network to be routed, then select the relevant Destination Network to enable Forwarding. For example, to configure a single Ethernet device as a cellular router: • The Source Network would be the Network Interface and the Destination Network would be Dial-Out/Cellular. IP masquerading is generally required if the console server will be routed to the Internet or if the external network it is being routed to does not have routing information about the internal network behind the console server. IP masquerading performs Source Network Address Translation (SNAT) on outgoing packets to make them appear as if they are from the console server (rather than devices on the internal network). When response packets come back to devices on the external network, the console server will translate the packet address back to the internal IP so that it is routed correctly. This allows the console server to provide full outgoing connectivity for internal devices using a single IP address on the external network. By default, IP masquerading is disabled for all networks. To enable masquerading: • Select Forwarding & Masquerading panel on the System: Firewall menu. • Check Enable IP Masquerading (SNAT) on the network interfaces where masquerading is to be enabled. Masquerading is typically applied to any interface that is connecting with a public network such as the Internet. 96
