30.4.3 Example 3: Multiple Public IP Addresses With Inside
Servers
In this example, there are 3 IGAs from our ISP. There are many departments but
two have their own FTP server. All departments share the same router. The
example will reserve one IGA for each department with an FTP server and all
departments use the other IGA. Map the FTP servers to the first two IGAs and the
other LAN traffic to the remaining IGA. Map the third IGA to an inside web server
and mail server. Four rules need to be configured, two bi-directional and two uni-
directional as follows.
