Figure 38 IDP Configuration for To VPN Traffic

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).
