Configuring IP Forwarding for Your Host

A host supporting one or more ChorusOS simulators must be configured to allow IP packets to be forwarded to simulators on the ChorusOS pseudo-network. The forwarding option allows your host to forward any IP packet coming from its Ethernet controller to the Ethernet pseudo-driver. This is required if you want remote machines to access ChorusOS simulators, as well as allowing ChorusOS simulators to access remote machines.

To activate the forwarding option at boot time, create an empty file called /etc/gateway. After you reboot, forwarding will be activated automatically.

If you do not wish to either activate the forwarding option at boot time, or reboot your host, enter the following command with super-user privileges:

# ndd -set /dev/ip ip_forwarding 1
