I need to connect with host in my private network by Border Manager from
public internet host.

BM pubIP:
BM prvIP:


1. host2 makes a connection to BM pubIP:portX
2. packet from host1 is NATed to host1
3. host1 sends reply to BM prvIP
4. BM sends the reply to host2

In some hardware routers this function is named "IP MAPPING". For example
one ASMAX router can map many ports from many hosts in private LAN to one
PUBLIC IP address and different ports.
Probably this is static NAT for public interface. But can I set the static
NAT for one public IP of BM if it serve a proxy service for private hosts?
Can I set many mappings to other hosts in my private LAN by only one public
IP of BM? How to?
