I have two NICs in my one of my network machines (Unit A). One NIC (NIC A, 10.10.10.n) is for a private network that communicates with another machine (Unit B), wihch has a NIC that also uses a 10.10.10.n address. The second NIC in Unit A (NIC B) is connected to my enterprise's network and has a 10.200.n.n address. However, from Unit B, which is connected to NIC A in Unit A, I can see machines on the NIC B (enterprise) network. While access to the machine's data isn't an issue as the credentials are not available, I'd prefer to avoid having the NIC B machines viewable on the machine that connects through NIC A. The NICs are not bridged in any way. I hope that I explained this understandably. Thanks.
