We have 1 cluster where we need to change physical cabling of External Interface on both members of cluster. IPs and netmask will be exactly the same for both members and cluster. The only thing what will be changed from FW point of view is physical interface.
Currently we have External interface eth4 and we need to change it to eth2.
I need to change Topology in Dashboard, set IP on eth2, delete IP from eth4, change management interface and push the policy.
Default route will be the same.
Is there any way how to do it without outage? We have dozens of VPNs established via External interface.
If I will do the job with IPs on Standby member only, modify Topology and push the firewall... how will cluster react? It will push the policy on both members or only on Standby ?
We are running R77.30.
