Configure NAT between 4 Networks ( OWA, Edge Transport, Interent User)

Level 1

Hi,

Current Setup:

Network 1    outside (with Public IP Pool)

Network 2    Inside  ( connected to Router and than LAN)

Network 3   DMZ ( Edge Transport Server 2013)

Network 4   Internet/Streaming (computers connected to direct internet)

 

Objectives: NAT 11.111.245.67 to DMZ( 172.16.2.10) with 25 and 110

                  NAT  11.111.245.67 to Inside (10.185.8.69) with 443 for OWA

                  Inside can commincate DMZ

                   Internet/streaming can use the internet without restriction

                  interent/streaming cannot access DMZ and Inside

Please see the configuration

 Inside can commincate DMZ --> It can by default


 Internet/streaming can use the internet without restriction} You need to achive this using NAT , ACL

 interent/streaming cannot access DMZ and Inside} It can't with Inside , because you have same security level by default it wont unless  you configured to permite traffic between same security level.
 
  HTH , please mark as answered if it solved your problem.
