Hello! We have the following infrastructure:

Exchange Hub Transport NLB cluster
ISA TMG server with 2 ISP's (2 NIC interfaces each connected to own ISP)

Exchange SMTP cluster is published trough NIC1.
Is it possible associate two MX records with IP addresses of NIC1 (MX 10) and NIC 2 (MX 20) and achieve high availability?
If yes, how to accomplish this?
Thanks.

Hi,
The ISP Redundancy feature wasn't designed to provide high availability to inbound connections.

ISP Redundancy is only supported to provide high availability to outbound traffic.

When you use 2 NICs, you must configure the Metrics on the Network Adapters and use one of the NICs (NIC with higher priority) to publish your SMTP.
