Cisco 1841 - Trying to assign all 5 static IPs to network

Discussion in 'Cisco' started by extremesanity, Feb 26, 2007.

  1. On my business SBC static plan I have 5 static ips.

    I have the 2wire modem setup as a bridge, a gateway address assigned
    to the cisco router, a public ip assigned to the cisco router, and a
    public ip assigned to the firewall that then does NAT to private

    I setup the cisco router to assign an IP from SBC automatically via
    PPPOE on the Dialer1 interface that is assigned to the 0/1 ethernet
    interface. The address assigned is xx.xx.xx.230/32.

    I TRY to set the 0/0 ethernet statically to xx.xx.xx.225, which is the subnet SBC provides me. The router
    throws an error: xx.xx.xx.224 overlaps with Dialer1.

    I can set the router to xx.xx.xx.225 or xx.xx.xx.226 with subnet, and everything works.

    However I need all of my 5 IP addresses. Setting the subnet mask to does not allow me the full range: 225 to 229.

    Anyone have any idea what is going on here?
