Enable Strict Multi-homing

For systems that are gateways to other domains, such as a firewall or a VPN node, strict multi-homing must be enabled. The hostmodel property controls the send and receive behavior for IP packets on a multi-homed system. Set strict mult-homing to 1 so that packets don't get accepted on a different interface. The default is 0.

1. Log in to one of the compute servers and access the host console as superuser.

   See Log into a Compute Server.

2. Set strict multi-homing to 1.
