Planning for Exchange 2013 DR. I have some queries on configuring DAG in my DR site.

Current setup:- 

Primary site:- (2MB,2 CAS)

DR Planning:-

One Mailbox,One CAS Server

In primary mailbox server, two nic card is there. One is for MAPI and other one is for DAG replication. In DAG replication NIC card there is no gateway. Primary site DAG working without any issues. In DR mailbox server two nic is there(One for Mapi and other for DAG replication). Problem iam facing is Primary site DAG NIC card not able to communicate with DR MBX server, since there is no gateway in replication NIC card. If I add the gateway in replication NIC, then it is communicating with DR MBX. But iam getting mutiple gateways warning message.

MY Query is:-

1) Is there any problem having multiple gateways in MBX server.

2) If there is no problem with multiple gateway, how to restrict the users traffic hitting DAG replication NIC card.

3) Is there any configuration required in failover cluster manger menu for DR.

4) Is there any way to check DAG(replication) traffic hitting which NIC card..

Thanks for your support...
