hi everyone,

We are running Exchange 2013 in a multi-tenant environment. I want to know if it is possible, for each tenant's domain, can I allocate a different IP (internal) for both send and receive connector that is different than the IP of Exchange server?

My plan is to allocate a public IP for each tenant, and NAT to different Internal IP, associate with the corresponded send and receive connector.

Is that even a possible option to do?

Thank everyone!

Hi 

Can you please let us know the requirement of doing this ?

To allocate seperate public ip's for each tenant will give you more cost 

Rather you can have a spam filter route all the mails to that spam filter from your hub and then from the hub you can route emails to the internet through one public ip which is more beneficial 

And there is no requirement  needed as far my knowledge is concerned to allocate different internal IP's for each tenant
