• Site-to-site VPN: A site-to-site VPN interconnects two sites, as an alternative
to a leased line, at a reduced cost. Figure 19-1 shows an example of a site to site VPN. • Client-to-site VPN: A client-to-site VPN (also known as a remote access VPN)
interconnects a remote user with a site, as an alternative to dial-up or ISDN connectivity,
at a reduced cost. Figure 19-2 shows an example of a client-to-site VPN. • With a full tunnel configuration you have all the end-user traffic
go through the VPN tunnel. • With a split tunnel configuration you don't have all the end-user
traffic go through the VPN tunnel. For example, you might choose to have just the traffic
that needs to access the corporate network sent through the VPN tunnel, while allowing
traffic destined for the Internet (perhaps Office 360 traffic) to bypass the tunnel.
Split tunneling is often an advantageous configuration because the bandwidth required
by the VPN connection (and the overhead associated with it) can be minimized. About The Author Anthony Sequeira, CCIE No. 15626, is a Cisco Certified Systems Instructor (CCSI) and author
