Direct Access to Servers in Router Mode
This example shows how to configure a virtual server to give direct access to the backend servers when
you are using router mode:
In router mode, any connection that does not hit a virtual server is dropped.

# The alias IP is only required in redundant configurations
# This is the IP address that the upstream router (the MSFC
# in this case) will use as next-hop to reach the
# backend servers
# See below for the static route added for this purpose.

# This serverfarm is not load balancing, but is simply
# routing the traffic according to the CSM routing tables
# The CSM routing table in this example is very simple,
# there is just a default gateway and 2 directly attached
# subnets.
#
# The "no nat server" is very important, since you do not
# want to rewrite the destination IP address when
# forwarding the traffic.
