A secure 'tunnel' is established and
as you are making use of an existing Internet connection, there
are no long distance phone charges or huge leased line costs
typical of LAN links. Our solutions supports industry standard
PPTP and IPSec VPN protocols, with DES/3DES encryption to link
to Teleworkers or remote offices.
In this example, we have two remote offices and one remote
teleworker. Everyone can see each other on their private network
addresses, whilst inter-site traffic is actually being carried
across the public Internet, wrapped up in a secure tunnel using
the public IP addresses for site-to-site transport.
