VPN and personal F/W Question

Background:

Cisco 3000 series VPN

No split tunneling allowed

Zone Alarm or Black Ice personal F/W

I thought that a personal firewall protects the VPN client from intruders during a VPN connection. Without a personal firewall, a client is vulnerable to access attempts during a VPN connection.

But I was told the following: "VPN implementation restricts communication to devices other than the computer itself and company's network for the duration of the VPN connection."

I thought that the client can still communicate on other open ports during a VPN session. Basically, a hacker can still make attempts to access the client on other ports during a VPN session.

What is correct? (Thank you.)

Re: VPN and personal F/W Question

With "split tunneling" enabled the client can communicate with outside networks and would use a firewall.
