Subj:   Re: Restricting IPs
From:   Coffing Christopher L

Great question...

Many of the users that I deal with see Teradata as many separate systems that could be used for different things, but currently is only being used for Teradata. Teradata is many systems, but these systems are all tied together to create a single system. So even though a user can connect and login to one of the nodes, it is still a global connection. They will be able to login to any of the nodes, so to speak.

So how can we protect against users logging into specific nodes? There are several different IP load balancers out there. F5, Cisco ect... We use this technology so the user points to a single IP address and in turn the IP "Sprayer" will connect them to a random node or the closest available node.

Firewalls are also another technology that will redirect IP addresses to target IP's and can do so based on the source IP/MAC.

Talk with your network team for assistance in securing the node IP addresses.
