Dear all,
I am a new comer to networking, my company's situation is similar to the following:

My question is:
1. how to restrict access between servers within the server farm?? e.g. in the community VLAN, I would like to block the access from DC01 to the database server.
2. If I set up a server running tripwire tool, how can I restrict each login to server within the server farm must first pass through the tripwire server, including access from an IP within the same community VLAN??
Thank and appreciate for any comments!!!
