[omniORB] How to force Omniorb 4.0 to use a certain IP address?

[Rick Sanden]

Both my client and server have two network cards. For both computers, one network card is used to access the intranet. The other card (for both) is used to create a fast peer to peer network for the client and server to talk to each other via omniorb. I am running windows 2000 on both the client and server. 
The client and server can find each other only if I enable the network cards in a certain order. If I enable the intranet first,on both, everything seems to work fine. If I enable the peer to peer cards first, callbacks start to fail. 
Is there a way  to force omniorb 4.0 to always look at the the peer to peer ip address and to forget about the intranet?

Thanks
