Setup and Environment
Host A is Ubuntu VM (GNS3). All other Servers are RedHat.
[Host A(x.x.y.b) --via-- Host B (x.x.y.a)] ----|---- [Host C (x.x.z.c) & Host D (x.x.z.d)]
- Host A is hosted in Host B as a VM. Using of static route all the other hosts in subnet x.x.y.* are able to ping Host A via Host B.
- Host C, D lie in a different subnet, hence cannot add static route via Host B.

- Adding routes in routers - I do not want to configure the routers
- VPN over SSH/PermitTunnel and Autossh - I might have to create 1 tunnel each for all the servers to connect.
