Configuring Protected Ports
There are situations where you want to provide internet access to users but
prevent them from accessing each other. To achieve this control, you can use
the protected-ports command. The command applies per-port, and filters the
outbound traffic from a port. This allows the configuration of two port groups
on a switchâ protected ports and unprotected ports. The ports have these
characteristics:
â   Traffic from protected ports is not forwarded to other protected ports.
â   Protected ports can communicate with unprotected ports, but not
with each other.
â   Unprotected ports can communicate with all ports.
â   The protected-ports command applies to logical ports (trunks as well
as untrunked ports)
Figure 9-15. Example of Protected Ports Command for Ports 4 and 5
To display information about which ports have been configured as protected
ports, enter this command:
ProCurve(config)# show protected-ports
Syntax: [no] protected-ports
Prevents the selected ports from communicating with each
other.
Default: All ports unprotected.
no protected-ports all
Clears the protection from all ports; all ports can now communicate
with each other

ProCurve(config)# protected-ports 4-5

Re: 2510-24

Ok.
So, if port 25 is connected to internet (uplink), port 10 is database server, port1,port2,port3 are web servers I can do the following:

port 1 unprotected
port 2 unprotected
port 3 unprotected

port 10 protected

port 25 protected

Doing so, port 1,2,3 can comunicate with all ports, port 10 can't comunicate with port 25 and the it will not have internet access.

Port 25 can't comunicate with port 10 so from Internet I can't access database server

Is true?

Re: 2510-24

Thanks for the reply.
Any security issue with this setup?
Vlans are more secure than protected ports?
