Menu 15.2.1 Specifying an Inside Server
21.5.3 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 unidirectional as follows.
1
Map the first IGA to the first inside FTP server for FTP traffic in both directions (
1 : 1
mapping, giving both local and global IP addresses).
2
Map the second IGA to our second inside FTP server for FTP traffic in both directions (
1
: 1
mapping, giving both local and global IP addresses).
3
Map the other outgoing LAN traffic to IGA3 (
Many : 1
mapping).
4
You also map your third IGA to the web server and mail server on the LAN. Type
Server
allows you to specify multiple servers, of different types, to other computers
behind NAT on the LAN.
The example situation looks somewhat like this:
