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

the default Internet to Local Network ACL Set blocks all traffic from the Internet, so you want

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.

Rule 1 forwards SMTP and POP traffic from the mail server and

Rule 2 forwards HTTP traffic from the proxy web server. This rule

will not generate a log.

matched rules in the ACL

Default Set.
