Linux gateway is connected with single NIC to net by leased line.I have another linux
box with ip 192.x which i am not able t o ping to 63.x ,shows network unreachable,but
at the same time other NT boxes with IP (192.x)can ping gataeway.So my concern is what
should I do so that they can ping.
I have made the necessary changes in the /etc/sysconfig/network file.what do you
suggest?
