Step 9. Configure Re-IP Rules
The Re-IP step of the wizard is available if you have selected the Replica re-IP option at the Name step of the wizard. You can use this step to configure Re-IP rules for Microsoft Windows VMs.
Re-IP rules can be helpful if the IP addressing scheme in the production site differs from the addressing scheme in the disaster recovery (DR) site. In this situation, you can configure a number of re‑IP rules for the replication job. When you perform failover, Veeam Backup & Replication will check if configured Re-IP rules apply for the VM replica. If a Re-IP rule applies to the VM replica, the VM replica will get a new IP address according to the new network mask, and you will be able to reach this VM replica in the DR site.
To configure a Re-IP rule:
- Click Add.
- In the Source VM section, describe an IP numbering scheme adopted in the source site. To facilitate configuration, Veeam Backup & Replication detects an IP address and subnet mask for the backup server and pre-populates values in the Source VM section.
- In the Target VM section, describe an IP numbering scheme adopted in the DR site. Specify an IP address, subnet mask and default gateway that will be used for VM replicas. If necessary, define the DNS and WINS server addresses.
- In the Description field, specify a brief outline of the rule or any related comments.
You can use the asterisk character (*) to specify a range of IP addresses, for example, 172.16.17.*.
