Exclamation Ldirectord and heartbeat with multiple IPs

So I have a question about heartbeat and ldirectord. This may be a simple question, but I don't know the exact answer so if I could get some help with this it would be greatly appreciated.

I am working on a project that has the following servers:

2 Linux directors each running ldirectord and heartbeat
3 web servers which are being load balanced via the Linux directors
Multiple other servers that the client has running for their business

There are 8 public or “virtual” IPs all used to get to various web pages, servers and services.
We will say the IPs range from 210.0.0.1 to 210.0.0.9 with netmask of 255.255.255.0
Internally they are running a standard 192.168.X.X network.

We are running a High Capacity High Availability and Load Balancing model for the setup using ldirectord and heartbeat. The picture below is a general setup



Anyways now down to the real question.

I am wondering if there is anything special we need to do with the /etc/ha.d/haresources file to accommodate for all the extra IPs. Or does the /etc/ha.d/ldirectord.cf file take care of the “virtual” IPs?

This is what the /etc/ha.d/haresources and the /etc/ha.d/ha.cf files currently look like.

/etc/ha.d/ha.cf

logfacility local0
bcast eth0 # Linux
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node LoadBalancer1
node LoadBalancer2
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster


/etc/ha.d/haresources

LoadBalancer1 \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master \
IPaddr2::210.0.0.1/24/eth0/210.0.0.255


What I am unsure of is if we need to add more IPs to the /etc/ha.d/haresources file since the client wants to be able to get to all of their servers via a public IP being routed through the linux directors.... PLEASE HELP!
