Connecting to the OBWI through a firewall
For AutoView 3050/3100/3200 switch installations that use the OBWI for access, four ports must
be opened in a firewall if outside access is desired.
In a typical configuration, as shown in Figure 2.3, the us
er’s computer is located outside of the
firewall, and the AutoView 3050/3100/3200 switch resides inside the firewall.
