First machine is called router, has gateway_enable="YES" and shows the following interfaces router# ifconfig bge0: flags=8843 metric 0 mtu 1500 options=8009b ether 00:50:45:5d:9a:bc inet 192.168.1.158 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (100baseTX ) status: active bge1: flags=8843 metric 0 mtu 1500 options=8009b ether 00:50:45:5d:9a:bd inet 192.168.17.17 netmask 0xffffff00 broadcast 192.168.17.255 media: Ethernet autoselect (none) status: no carrier .. and the second machine called client: client# ifconfig bge0: flags=8843 metric 0 mtu 1500 options=8009b ether 00:50:45:5d:c6:ec inet 192.168.1.157 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet autoselect (100baseTX ) status: active bge1: flags=8843 metric 0 mtu 1500 options=8009b ether 00:50:45:5d:c6:ed media: Ethernet autoselect (none) status: no carrier .. in this case the second machine (client) has two network adapters but bge1 has no ip assigned and is down.
