Chapter 4 Remote Office

Access Configuration

In order for the local LAN users to access a remote LAN, you need to

configure a connection profile for the router on each site (the remote router

and the Broadband Router). Note that the remote site does not have to have a

SMC7301TA router, and may not be configurable by the local administrator. In

either case , make sure the configuration of SMC7301TA matches the

requirements of the remote site.

these steps:

Step 1:

Select

Access to/from Remote Site
