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

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

To add a default route with the CLI:

config vdom

edit VDOM-A

config router static

edit 0

set gateway 172.20.201.7

set device wan1

next

end

next

end

To add the security policy in the GUI:

1. Connect to VDOM-A.
2. Go to Policy & Objects > IPv4 Policy and create a new policy.
3. Enter the following information:

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

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

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

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. Connect to VDOM-B.
2. Go to Policy & Objects > IPv4 Policy and create a new policy.
3. Enter the following information:

   Name	Access-server
   Incoming Interface	wan2
   Outgoing Interface	port2
   Source Address	all
   Destination Address	FTP-server
   Schedule	always
   Service	FTP
   Action	ACCEPT

To add the security policy with the CLI:

config vdom

edit VDOM-B

config firewall policy

edit 0

set name Access-server

set srcintf wan2

set dstintf port2

set srcaddr all

set dstaddr FTP-server-VIP

set action accept

set schedule always

set service FTP

next

end

next
