>&#13;There are several answers to that question. It really depends on
your network layout. The most common configuration is to have a single
main internal network with remote nodes using VPN to gain full access
to the central net. The remote nodes are commonly remote offices or
employees working from home. You can also link two small (or
large) networks to form an even larger single network.
