Our client has two sites, internal and remote.

Internal has installed a Server, the remote site is the client subnet of this server.

The router which is connecting the server has other department subnet connection as well. And also connect internal routers.

We deploy static route between these two sites, and EIGRP for the internal network.

Static route is redistributed into EIGRP.

My question is in the internal router, how to control that in the server site, only the server can use the static route which is connecting to his subnet.
