This function supports the creation of multiple virtual IP interfaces on this router. It helps to connect two or more local networks to the ISP or a remote node. In this case, an internal router is not required.
Click Add to add a new IP alias.
•IP Address: Specify an IP address on this virtual interface.
•SubNetmask: Specify a subnet mask on this virtual interface.
•Security Interface: Specify the firewall setting on this virtual interface.
•Internal: The network is behind NAT. All traffic will translate network address when being sent out to the Internet if NAT is enabled.
•External: There is no NAT on this IP interface and it is connecting to the Internet directly. This is used when provided with multiple public IP addresses by ISP. In this case, you can use the public IP address in the local network with gateway IP address point to the IP address on this interface.
•DMZ: Specify this network to the DMZ area. There is no NAT on this interface.
