DHCP Issue being a client and server

  • 1.  DHCP Issue being a client and server

    Posted 05-16-2014 10:35

    I'm trying to:

     

    Get a v4 address and a v6 address from my ISP

    Serve DHCP addresses to my internal zone

     

    Aparently I'm doing something either wrong or unsupported here. When I put in the system services dhcp configutation it says I have incompatabilities with my fe-0/0/0 interface being a dhcp client.

     

    Any suggestions?

     

    Thanks

     

     

    version 12.1X46-D15.3;
    system {
        services {
            ssh {
                protocol-version v2;
            }
            dhcp {
                name-server {
                    8.8.8.8;
                    8.8.4.4;
                }
                router {
                    192.168.1.254;
                }
                pool 192.168.1.0/24 {
                    address-range low 192.168.1.100 high 192.168.1.149;
                }

    I'd stop using the system services dhcp hierarchy and start using "set access address-assignment" for DHCP.  Check out my post here:

    Changing to set access address-assignment hierarchy worked great thanks!

    What is the ISP side interface is Dynamic ( DHCP) , I tried this new method because I want a specific host on my LAN pool to get the same IP everytime ( static binding) but I lost the IP on external interface ( in my case fe-0/0/7)

     

     

        pool Wired {

            family inet {

                network 172.24.10.0/24;

                range wired {

                    low 172.24.10.20;       

                    high 172.24.10.250;     

                }                           

                dhcp-attributes {           

                    name-server {           

                        75.75.75.75;        

                        172.24.10.1;        

                    }                       

                    router {                

                        172.24.10.1;        

                    }                       

                }                           

                host Macbook {              

                    hardware-address xx.xx.xx.xx;

                    ip-address 172.24.10.26;

                }   

                                   

    cq# show | display set                

    set interfaces fe-0/0/7 description "To Internet Modem"

    set interfaces fe-0/0/7 unit 0 family inet dhcp-client update-server

    Hi hayyankk,

     

    When you say that you have the same issue, you mean that you have both DHCP server and client configured and its not working? (thats the issue of this ppost) If not, maybe you could open a new forum post for your specific question/issue.

    set interfaces fe-0/0/0 unit 0 family inet dhcp

    set interfaces fe-0/0/0 unit 0 family inet6 dhcp

    set security zones security-zone untrust interfaces fe-0/0/0.0 host-inbound-traffic system-services dhcp

    Assuming that your fe-0/0/0 is connected to the  ISP and it is in the zone named untrust (put in relevant zone) Add additional services and protocols if required.
