Step 8. Now you want an FTP server (IP of 192.168.10.3) to be accessible from the Internet. Remember

to create a hole for this server. Click the Internet link to see its Rule Summary screen. Now
click an available No. (rule number) radio button, then click Edit to bring up the Rule
Config(uration) screen. Now click on the DestAdd button under the Destination Address box
and enter the IP of FTP server One (192.168.10.3). Follow the same procedure as shown in
Figure 19-3and Figure 19-4.
Don’t forget to click Apply to save your settings
back to the ZyWALL.
