Updating Cluster External IP on NG 55 AI QUERY

[Nigel Cullen]

Hi,

We have a clusters pair of Nokia 330 boxes running NG 55 AI, IPSO 3.8

I need to change the External IP address on the cluster.
The licences for the pair of Nokia units are registered using their internal IP addresses, which are not changing.

I have listed below the steps I believe I need to perform to complete the change, is there any 'gotcha's' I've missed ?

1/ Logon to each firewall unit in turn as admin via Voyager, create backup of each firewall config.
2/ Got to Interfaces, add new IP – input new interface address in new range on External interface.
3/ Delete old External IP address , apply and save.
4/ logon to firewall cluster using cadmin
5/ goto Clustering Setup, enter new External cluster ip address
6/ Goto Static Routes, change Default route to point to new External IP gateway
7/ save and apply
8/ Logon to Smartcenter
9/ Create Database Revison control
10/ Goto Network Objects, Checkpoint, firewall cluster object
11/ goto fw1 node, topology, change External IP to match 2 above
12/ repeat for fw2 node
13/ goto Firewall Cluster object, topology, change External IP to match 5 above.
14/ Edit Nodes that use NAT to use new External ip address
15/ save and push policy

From what I have seen in the manuals, this should be the correct process, is there anything else I need to be aware of ?

Any help gratefully received !


Cheers
