Hello,

I have a cascading cluster built of 2 LPARs each one having 2 service
addresses (one for internal communication and second one for customer
access)

Two of service addresses are in network 10.1.1.0/24 and 2 in network
10.1.2.0/24.

Node1:
10.1.1.7
10.1.2.7
default gateway: 10.1.1.2

Node2:
10.1.1.17
10.1.2.17
default gateway: 10.1.1.2

When node1 is down and all resource groups are on node2 I need to have
10.1.1.7 as a source address because some of remote machines talk only
with this address.

Status of node2 after takeover (node1 crashed)

Has anyone idea how to handle with this problem? I just need after
takeover that source is address of en5 instead of en1 (both are in the
same network)
