  • Simple routing question

    I have an issue with a cisco 1750 router.

    We use SnapGear 300 appliances at our remote offices.

    One of our offices can only get a T1 line at their site so we plan on putting a cisco 1750 with a T1 CSU card in but we still need the 300 appliance to be in place.

    I have some Cisco experience but that was years ago and I can't seem to get this fully functional.

    I have the cisco able to ping addresses on the internet and it can ping the Snapgear router. The Snapgear router can ping the cisco router but not out to the internet? The workstation is able to ping the Snapgear and the Cisco but not the internet.

    Currently I have no access-lists applied.

    I have the default route out the Serial interface on the Cisco router and one ip route, 192.168.0.0 addresses to the 10.1.1.2 IP.

    I have attached a diagram.


    Thank you for your help,
    Major

      The cisco, there is only one public IP

      How is would that be configured?

        If just one public ip you can just overload on that outside interface


        Configure ACL

        access-list 1 permit 192.168.0.0 (permits the subnets allowed to be natted)

        ip nat inside source list 1 interface "your outside interface" overload

        On the cisco lan facing interface:

        ip nat inside

        On the cisco outside interface facing the ISP

        ip nat outside


        Example: Assume the outside interface is s0/0 and inside is fa0/0

        int s0/0
        ip nat outside

        int fa0/0
        ip nat inside
