NAT and transparent mode

In this example, VDOM-A uses NAT mode and VDOM-B uses transparent mode.

This configuration requires the following steps:

1. Configure VDOM-A
2. Configure VDOM-B

Configure VDOM-A

VDOM-A allows connections from devices on the internal network to the Internet. WAN 1 and port 1 are assigned to this VDOM.

The per-VDOM configuration for VDOM-A includes the following:

• A firewall address for the internal network
• A static route to the ISP gateway
• A security policy allowing the internal network to access the Internet

All procedures in this section require you to connect to VDOM-A, either using a global or per-VDOM administrator account.

To add the firewall addresses in the GUI:

1. Go to Policy & Objects > Addresses and create a new address.
2. Enter the following information:

   Name	internal-network
   Type	Subnet
   Subnet / IP Range	192.168.10.0/24
   Interface	port1
   Show in Address List	enabled

3. Click OK.

To add the firewall addresses with the CLI:

config vdom
    edit VDOM-A
        config firewall address
            edit internal-network
                set associated-interface port1
                set subnet 192.168.10.0 255.255.255.0
            next
        end
    next
end

To add a default route in the GUI:

1. Go to Network > Static Routes and create a new route.
2. Enter the following information:

   Destination	Subnet
   IP address	0.0.0.0/0.0.0.0
   Gateway	172.20.201.7
   Interface	wan1
   Distance	10

3. Click OK.

To add a default route with the CLI:

config vdom
    edit VDOM-A
        config firewall address
            edit 0
                set gateway 172.20.201.7
                set device wan1
            next
        end
    next
end

To add the security policy in the GUI:

1. Go to Policy & Objects > Firewall Policy and create a new policy.
2. Enter the following information:

   Name	VDOM-A-Internet
   Incoming Interface	port1
   Outgoing Interface	wan1
   Source	internal-network
   Destination	all
   Schedule	always
   Service	ALL
   Action	ACCEPT
   NAT	enabled

3. Click OK.

To add the security policy with the CLI:

config vdom
    edit VDOM-A
        config firewall policy
            edit 0
                set name VDOM-A-Internet
                set srcintf port1
                set dstintf wan1
                set srcaddr internal-network
                set dstaddr all
                set action accept
                set schedule always
                set service ALL
                set nat enable
            next
        end
    next
end

Configure VDOM-B

VDOM-B allows external connections to reach an internal FTP server. WAN 2 and port 2 are assigned to this VDOM.

The per-VDOM configuration for VDOM-B includes the following:

• A firewall address for the FTP server
• A static route to the ISP gateway
• A security policy allowing external traffic to reach the FTP server

All procedures in this section require you to connect to VDOM-B, either using a global or per-VDOM administrator account.

To add the firewall addresses in the GUI:

1. Go to Policy & Objects > Addresses and create a new address.
2. Enter the following information:

   Address Name	FTP-server
   Type	Subnet
   Subnet / IP Range	172.25.177.42/32
   Interface	port2
   Show in Address List	enabled

3. Click OK.

To add the firewall addresses with the CLI:

config vdom
    edit VDOM-B
        config firewall address
            edit FTP-server
                set associated-interface port2
                set subnet 172.25.177.42 255.255.255.255
            next
        end
    next
end

To add a default route in the GUI:

1. Go to Network > Routing Table and create a new route.
2. Enter the following information:

   Destination	Subnet
   IP address	0.0.0.0/0.0.0.0
   Gateway	172.20.10.10

3. Click OK.

To add a default route with the CLI:

config vdom
    edit VDOM-B
        config router static
            edit 0
                set gateway 172.20.10.10
            next
        end
    next
end

To add the security policy in the GUI:

1. Go to Policy & Objects > Firewall Policy and create a new policy.
2. Enter the following information:

   Name	Access-server
   Incoming Interface	wan2
   Outgoing Interface	port2
   Source	all
   Destination	FTP-server
   Schedule	always

                set dstintf port2
                set srcaddr all
                set dstaddr FTP-server-VIP
