hostmodel (ipv4 or ipv6)

Description

Controls send and receive behavior for IPv4 or IPv6 packets on a multi-homed system. This property can have the following values: weak, strong, and src-priority. The default value is weak.

Default

weak

Range

weak, strong, or src-priority

• weak

  • Outgoing packets - The source address of the packet going out need not match the address configured on the outgoing interface.

  • Incoming packets - The destination address of the incoming packet need not match the address configured on the incoming interface.

• strong

  • Outgoing packets - The source address of the packet going out must match the address configured on the outgoing interface.

  • Incoming packets - The destination address of the incoming packet must match the address configured on the incoming interface.

• src-priority

  • Outgoing packets - If multiple routes for the IP destination in the packet are available, the system prefers routes where the IP source address in the packet is configured on the outgoing interface.

    If no such route is available, the system falls back to selecting the best route, as with the weak ES case.

  • Incoming packets - The destination address of the incoming packet must be configured on any one of the host's interface.

Dynamic?

Yes

When to Change

If a machine has interfaces that cross strict networking domains (for example, a firewall or a VPN node), set this parameter to strong.
