Static NAT Exchange 2010 (CAS servers)

I am afraind this question has been asked many times but I would like for someone to give me some advise.

We are currently running Exchange 2003. We are going to migrate to Exchange 2010 soon.

Our goal is to deploy 4 servers. 2 servers with CAS/HUB and 2 MBX servers (DAG)

We don't have the budget for 2 TMG servers. We were thinking about using a static nat (public IP nating to private IP for 443) poiting to the internal CAS array IP.

Is that something that is going to work? Is someone running production with this in place?

Yes, this works. I have it running in production at the moment. I take it this is how you have Exchange 2003 configured at the moment?

Yes. This is the way we have Exchange 2003 configured. What is the size of your Exchange env. how many servers, mailboxes? I understand there are some caveats when running this configuration, have you find any issues?

What type of NAT rule have you configured? what type of firewall do you have? Are you poiting natting to the VIP for the NLB CAS Array?

it works 100% and this is the way it should be done, the link you pointed to is talking about something different, it is just stating that the cas array name should not be resolvable from the internet (which is true) but you can nat a public IP to the NLB IP of your cas servers
