Exchange 2013 Receive Connectors

Hey guys

Quick question.  A customer of mine recently installed 3 exchange 2013 servers in his network (two locally and one remotely over VPN) and it is working like a charm. He has all three in a DAG and the databases are replicating across all three with zero issues.  Now, I just happen to be digging around and I noticed that all three have their receive connectors enabled.  If one of them goes down, does that mean that the next one in line can receive emails if I have the MX records setup to forward to a different IP address? (the client has multiple public IP's on his router).  If so, that would of course be awesome :-)

if you dont have a load balancer in place you can create one more MX record with higher priority.
So if the 1st MX record is not reachable it will reach the second one.
e.g. 1st MX   record                  mail.domain.com         pointed to 1.1.1.1       Priority 10
        2nd MX record                  mail2.domain.com       pointed to 1.1.1.2      Priority 20
And  do a 1-1 NAT
NAT 1.1.1.1 to the first server   (1.1.1.1-->192.168.1.101)
NAT 1.1.1.2 to the second server (1.1.1.2-->192.168.1.102)
in this
1.1.1.1(External)  and 192.168.1.101(Internal) are 1st Exchange IPs
1.1.1.2(External)  and 192.168.1.102(Internal) are 2nd Exchange IPs

You can shut down the first server to see emails received in second server.
Make sure both has antispam installed or you should have antispam filtering on your firewall/router

But the recommend way is to use a load balancer.

Perfect!!  I will do that this weekend.  Just curious though do I have to do 1 - 1 NAT or can I just open up the various ports on my firewall?  My firewall supports as many public IPs as I can get...
