    Hi,

    I’m trying to configure a cisco 1921 with our new provider and I am having some problems. With the config below I can ping hosts from the router, but not from the private ip’s. The info I got from the ISP:

    wan route: x.x.x.220/30
    isp ip address: x.x.x.221
    customer ip address: x.x.x.222
    public ip’s: y.y.y.224/29

    Any help would be appreciated.

    Philip
