Veeam re-ip and replication to LAN

Hi

Have the latest Veeam, Version,  replicated a VM  From the LAN to the DMZ as a test, wanted to test the re-ip and performance.

It was the first time, so the whole VM having size 40GB was replicated to the DMZ,

Veeam parameters used:  LAN,   and optimal Compression

The Source VM is located on Host ESXi  5.1 into  Storage  Equalogic PS4100 

The Destination VM was built on Host ESXi  5.1 (in DMZ)  Two locals disks Scasi Raid 1

i set  the   re-ip option and gave  the new  IP Address and Mask,   but  didn't change

Performance on all VM's on the Source Host ESXi into Storage was so slow that even RDP could not be done,

not only during the replication time, but also afterwards,

Any ideal

Thanks
