Ssh can also be used to create a local access that is forwarded to a
remote access throught the ssh protocol. For example you can use ssh to
securely map a local acces to a remote POP server:
local:localport ==> local:ssh ~~~~~ ssh port forwarding ~~~~~ remote:ssh
==> remote:pop
And when you connect to local:localip you are transparently/securely
connected to remote:pop

I think that it is'nt necessery to have the default router to the load
balancer when using ssh because when the RS address is the same that the
VS address (differents ports)
