Limiting Service that pass through F5

These are the basic steps:

1) Create Nodes

2) Create Pool

3) Add Members to Pool

3a) A Member is a Node with port

4) Create Virtual Server

4a) Add Pool to Virtual Server

Roughly speaking, if Member 192.168.140.1:80 exists in a Pool and 192.168.140.1:443 does not, then the Virtual Server will answer to port 80 traffic, but not answer to port 443 traffic. If 192.168.140.1:25 doesn't exist in the Pool, then the Virtual Server won't answer to port 25 traffic.

Good luck!
