Yes, it does. As I mentioned, the DNS for the server points the the 192 address. The session is initiated from the client to the server via this address. When the server starts the backups, they come across the public 128.172.6.201 connection to the server, not the 192 connection. This is the problem. I want the TSM server to receive the backups across the 192 connection, not the 128 connection. Everything is established across the 192 but when the backups flow, the go across the 128.

If the ping fails then you do not have a connection to 192.168.20.44 and no amount of port opening, aliasing, etc. can get your traffic to flow to and from 192.168.20.44. H.

The client talks to the server (and vice-versa) just fine, if the ports are not blocked. I want the server to use its private subnet to talk to the client, not its public connection. After all, this can be forced on the client via TCPNODEADDRESS, can the server do the same. Yes, I believe the private network is routed since lots of systems, both physically on the same and not in the same building, connect to the TSM server, just fine.
