We require to reach among the DMZ net web servers which is 10.0.10100 from the Net for any type of kind of kind of choices. (Please bear in mind that this conditions is making the most of v4.0, develop0535,120511( MR3 Location 7) ).

Authorization instance the Net IP address obstructs that we receive from the Get to company are 2002001000/24 along with we prefer to NAT the IP Address 200200100100 right into our internet internet server IP Address 10010100

How configure nat fortigate

Prior to we can access the NAT IP Address, we call for to develop an Online IP making the most of the sticking to tasks:

    • Outdoors IP Address/Range: 200200100100
    • Mapped IP Address/Range: 10010100
    • No Port Forwarding Selected

After ending up develop the Digital IP after that Develop the Method making the most of the sticking to tasks:

  1. Greater Than Most Likely To Method > Method > Method along with option Establish New
  2. Full the sticking to along with option ALRIGHT
  3. Below is the kind:
    • Resource Interface/Zone: wan1
    • Resource Address: All
    • Location Interface/Zone: Internal
    • Location Address: Web_Server_NAT (option from the one we have actually truly developed on above tasks)
