Internet Storage Name Service (iSNS) Firewall exception

Hello

IsNs

This service allows for central registration of an iSCSI environment. Discovering available targets on the network.

However, a couple of commands are needed on the iSCSI initiators prior to starting using IsNs

If the Isns DHCP is not configured. Clients must be registered manually with the Iscsicli command.

Workaround

Assuming we have done a proper ICSI installation on the target server & the IsnS feature

and added the target server to the initiator.

We will perform the following command on the ICSI initiator, however, it will fail as per the firewall config.

to enable iSNS traffic through the firewall.

Once complete we can go ahead and run

iscsicli  addisnsserver “target sever

Once done on the target server we will be able to see the following:
