Example 1

In Figure 18, the ISP is configured to create a tunnel from the ISP’s access 
server to the central site. 

This method can also be used for a remote office if you do not want to 
configure tunneling on the bridge/router at the remote office.

Figure 18   

ISP to Central Site Tunnel

The connection process typically follows this order:

■

The remote user (the client) dials the ISP.

■

The ISP assigns an IP address to the remote user client.

■

The ISP checks its authentication server for the user, and creates a 
PPTP (or L2TP) tunnel to the central site based on authentication data.

■

The central site checks its authentication server to verify that this user 
can access the network and forwards the data.

No special configuration is required on the remote user computer except 
the configuration required to dial into the ISP’s access server.

At the central site, follow these steps:

1

Configure the L2Tunnel Service (see the Configuring L2Tunnel 
Connections chapter in 

Using Enterprise OS Software

) to enable the 

PathBuilder switch as a tunnel terminator.

2

Configure the firewall device (if present), or the PathBuilder switch, to 
allow tunnel traffic through (see the Building Internet Firewalls chapter in 

Using Enterprise OS Software

).
