In Lab we have two hosts say A and B. host A has two NIC and host B has single NIC (see below diagram for network topology)

NIC-1 of host A is connected to lab network and

NIC-2 of host A is connected directly (end-to-end) to host B

            ----------
            |         | -> NIC1                  ------> Lab Network (10.203.194.0/24)
            |         |    (eth0 - 10.203.194.247/24)
            | host A  |                                          ----------
            |         | -> NIC2                  -------> NIC1   | host B  | 
            -----------   (eth1 - 10.203.209.230/24)             -----------
                                                             (eth0 - 10.203.194.163/24)

From host A, I was able to ping 'lab network' whereas I couldn't connect/ping host B (10.203.194.163). I find a routing table of host A has default gw to lab network.

What changes were required to connect Lab network and host B FROM host A.
