Cisco VPN and ZoneAlarm Firewall

Hello colleagues,

I’d like to look for your comments about an issue that I’ve with my VPN connection.
I’ve an IBM notebook with Windows 2000 and I’m using a Cisco VPN client to establish my VPN connection.
My problem is that when I’m connected by modem to internet and with the VPN enabled I can’t have running the ZoneAlarm firewall. Because if I do that I can’t establish the VPN connection.

Do you have any suggestions that let me run the zonealarm firewall while using the Cisco VPN client ?

Thanks .
