Hi @R_Sharma, You said "concern- If multiple sources will be NATted on Palo Alto, the same sources still have the need to access server A which is in DMZ which will impact the access if we NAT the source, won't it?? The risk of outage matters a lot to production." No, the source NAT rule for the traffic to server B will not affect the traffic to serve A. It really doesn't matter that same sources are trying to reach A or B. The key point here is the destination. - Think of the NAT rules as traffic rules - you are configuring match critires (source, destination, port) and then action for the matched traffic. - PA NAT rules by their nature are conditional, because you have to specify the source zone, IP, deistiona zone, IP and port for the traffic that you want to NAT. Then you are specifiing the action - source or destination NAT (or both) for the traffic that matched So if you create NAT rule that specify NATed_server_B address as destionation address for your matching critires only, this rule will not match any traffic to server A (or NATed_server_A). Check again the config from my previous post.
