Ip Alias - Billion BiPAC 7401VGP R3 User Manual

IP Alias

This function enables the creation of multiple virtual IP interfaces for this router. It helps to connect two
or more local networks to the ISP or remote node. In this case, an internal router is not required.
IP Address: Specify an IP address for this virtual interface.
Netmask: Specify a subnet mask for this virtual interface
Security Interface: Specify the firewall setting for this virtual interface.
Internal: This mean the network is behind NAT. All traffic will do network address translation
when sending out data to the Internet if NAT is enabled.
External: This means there is no NAT on this IP interface and it is connected directly to the
Internet. This function is mostly used when you are provided with multiple public IP addresses
by the ISP. In this case, you can use the public IP address in the local network whose gateway
IP address points to the IP address on this interface.
DMZ: Specify this network to a DMZ area. There is no NAT on this interface.
