  • Cisco 877 config question

    Hi there,

    I recently bought a Cisco 877 router and using the web-based interface, managed to get the router working. Access to the internet as well as NAT to a server in the LAN via port forwarding is working fine.

    I was also given another set of IPs from the ISP for me to use with my servers, how do I configure the 877 to recognise and allow this range of IPs to be used in my network.

    example.

    ISP WAN IP: 83.120.xxx.10
    Router WAN IP: 83.120.xxx.11

    available IPs: 83.122.xxx.1-14

    The router's WAN is set to 83.120.xxx.11, the next hop is to the ISP at xxx.10

    I want to be able to use the available IPs and map them to devices in my network, either directly or through a firewall.


    I would really appreciate some help on this as it has stumped me for the last few days already.

    thanks in advance.

    Nevermind. by using the full SDM, i could add in the additional IPs, though i think there should be a better way to do it then this.

      Hi


      a little example...


      wan ip of the router 230.20.20.1 255.255.255.252
      Ip os the ISP 230.20.20.2 255.255.255.252

      now you need a /29 about 6 public ips 230.30.1.0/29

      in the interface vlanx
      ip address 230.30.1.1 255.255.255.248

      ip route 230.30.1.0 255.255.255.248 230.30.1.1

      Remember your ISP to route 230.30.1.0/29 to 230.20.20.0/30
