With these settings, namely GATEWAY2=..., how the arbitration is done (in networks stack) which of gateways is used for packets to be sent outside of networks the machine is on? As far as I know FreeBSD, there can be only one gateway (BTW, synonym: default gateway). Theoretically, the machine can have more than one gateway, but for that you need to have specially configured firewall/nat. Is this somehow different in Linux, and Linux does that auto-magically?
