Configuring the allowed subnets
Allowed subnets are like a firewall. Any hosts that are not in the allowed subnets has no access to the IRE MSDP server. Ensure that the IRE primary server is in the allowed subnets, otherwise you lose the control to the IRE MSDP server from the web UI. The computer you use to configure the IRE also must be in the allowed subnets.
Note:
For Flex Scale, the allowed subnets protect the entire cluster including the nodes, the NetBackup servers, and MSDP engines. Ensure that all the subnets, which need to access the cluster are in the allowed subnets.
To configure the allowed subnets
- On the left, click Storage > Disk storage.
- Click the Storage servers tab.
- Click on the MSDP storage server that you want to configure.
- Under Isolated Recovery Environment > Allowed subnets, click Add subnet.
- Select IPv4 or IPv6 and type the IP address of the subnet and click Add to list.
- Add all the subnets in the IRE domain that are required to access the MSDP server and click Save.
