Hello,

I have a CAS, MBX and Edge all separate in exchange 2013. I have one public IP NATed to internal Edge server private IP. I have issued certificates for OWA, active sync and would like to access mails from internet. I need to know how to finalise the setup so that it uses the same published IP used for Edge server.

If I ask my service provider to redirect my OWA URL to the same Edge server public IP, what is most likely going to happen?

Thanks,

Joel

Hello

tip: in firewall set forward tcp 25 to Edge and 443 to CAS
and set external urls and test connect with: https://testconnectivity.microsoft.com/

Hello Sneff,

Are you implying that I need to have two IP public addresses for that? Currently I only have one. Please note that CAS is not in the DMZ, its in the private network.

Regards,

Hello

not need two ip

only in firewall create two port forward.

Hello,

Not so clear.

EXample of a scenario happening,

Currently our support  ISP is redirecting our servername to public IP w.x.y.z, and our firewall is receiving port 25 smtp to allow to EDGE server. The edge public IP is NATed to Edge server private IP.

The OWA URL is in CAS server and is having private ip in the private network, not in DMZ and not NATed.

kindly advise me again.

Thanks

Hello

you need talk with firewall support. need only 443 tcp port to point the cas server and 25 to edge.
