For the Public IP Area
1. IP address to the endpoint is based on the first router .
2. For this setup, Public Area will not be protected from threat, cannot be managed by NGAF and have security consent since connection is direct to the first router.
3. Static IP for the 3 router in the Public Area
4. Default gateway IP address same with first router

For the DMZ Zone
1. IP address of the server is based on the NGAF
2. Default gateway IP addresssame with first router

Is this answer helpful?

hi! imo exposing public area to internet without any AF is not a good idea

Yes, IP re-addressing is a must.

Router:
1. interface facing the ISP
2. interface facing the NGAF

NGAF:
1. interface facing the Router
2. interface facing the Servers


Although the design is not totally wrong, you don't maximize the protection and you leave the Switch and other Routers unprotected.

It is not ideal design proposal because other network doesn't have security.

Your current topology is better than the change you want.

Your current diagram is the recommended design

Dont change your current production design. It is very risky.
