4.2 Firewall Rule for VPN Example

The firewall provides even more fine-tuned control for VPN tunnels. You can configure
default and custom firewall rules for VPN packets.
Take the following example. You have a LAN FTP server with IP address 192.168.1.4 behind
device A. You could configure a VPN rule to allow the network behind device B to access
your LAN FTP server through a VPN tunnel. Now, if you don't want other services like chat
or e-mail going to the FTP server, you can configure firewall rules that allow only FTP traffic
to come from VPN tunnels to the FTP server. Furthermore, you can configure the firewall rule
so that only the network behind device B can access the FTP server through a VPN tunnel (not
other remote networks that have VPN tunnels with the ZyWALL).
