Outgoing connections from a cluster node

we have setup a two node cluster using SG A.11.20 running on HP-UX 11.31.  Packages run only on one node with failover to another node (i.e. active/standby). An ip address for the cluster (ie. VIP) has been established via the ip_subnet and ip_address parameters in a package configuration file.

 

When connections are initiated from an external host to a node in the cluster, we use the IP address of the cluster. However when connections are established from within the active node, the SG's cmnetd does not perform a NAT functionality and the external host which has knowledge of the cluster IP at an application level rejects the incoming connection since it finds a different source ip that that of the cluster. 

 

Is there any SG configuration parameter that will fix this?
