Multi-homed Hosts¶
Hosts that have more than one network interface usually have one Internet Protocol (IP) address for each interface. Such hosts are called multi-homed hosts.
When a host is multi-homed host, different network exits can be specified for routes of different services as required.
Limitation
Multiple network interface configurations are only supported on Linux systems.
interface
Option¶
Use the interface
option to specify the network exit to use. The value of the interface
option can be either a network interface name (such as eth0
) or the IP address (IPv4 or IPv6) of a network interface.
Forwarding Chain¶
If a forwarding chain is used, a network exit needs to be set up at the first level hop of the forwarding chain or on a node within it.
If the interface
option is not set on the node, the option on the hop is used.
The interface
option on the command line corresponds to the option on the hop.
Direct Connection Mode¶
If the service does not need to use an upper-stream proxy, you can use Virtual Node to allow the service to use multiple network interfaces for load balancing.
