RAC node connected to outside DB and pass 2 IP address

Question

Experts,
we have a 4 nodes 11.1 RAC at red hat
As we know each node have 3 IP. --public, vip and privated IP.
it works well in domain inside network.
But we get a problem when try to connect to outside network client's database.
the connection string pass 2 IPs to client firewall (based on network monitor).
listener log show that connection is OK. But Conection is still blocked by client's firewall side.
The client network staff told us that we passed two IP address during connected connection.
Could some experts explain why does the RAC node's connected requested passs two IP to client database?
It is only discovered by network staff. we could not see 2 IP information in listener log file.
Is it our firewall NAT setting issue? or client firewall NAT setting issue
Thanks
Jim

Hi Experts
The Two IP addresses that were being passed were one of the load balancer and one of the db server. the load balancer was supposed to mask the load balancer IP address and only pass the db IP address. Somehow, we were sending both IP to client database--outside network. But IT works well in inter network side. How to eliminate the load balancer IP address from coming to client network firewall --to client database server side?
I looking for help!
