Here, each organization gets a virtual system of its own. These connect to the
main
routing table
using pairs of loopback interfaces. The routing tables would have the following entries:
Routing Table main

For each connection between a pair of virtual systems, a pair of loopback interfaces is required,
one for each system. When traffic is sent through
main-vs1
, it arrives on
vs1-main
. When traffic is
sent through
vs1-main
, it is received on
main-vs1
. This is exactly the same as with two NetDefend
Firewalls and two interfaces, one on each, with a connection between them.
The
Routing Table Membership
setting means that if a connection arrives on an interface, it will be
routed according to the routing table that the interface is a member of.
