  • 1.  basic dhcp not working

    Posted 10-19-2011 10:20

    Hi,

     

    I can't find what I'm doing wrong.  I've got an SRX210 that I'm trying to run DHCP on in the Trust Zone. If I connect myself to fa-0/0/5, I don't get an IP address and run show system services dhcp statistics shows this:

     

    Packets dropped:
    Total 257

    Messages received:

    DHCPRELEASE 0
    DHCPREQUEST 0

    Messages sent:
    BOOTREPLY 0
    DHCPOFFER 0
    DHCPACK 0
    DHCPNAK 0

     

    I think this is the only relevant part of the configuration:

     

    root@firewall# show system services dhcp
    pool 10.10.0.0/24 {
    address-range low 10.10.0.10 high 10.10.0.100;
    maximum-lease-time 1209600;
    default-lease-time 432000;
    domain-search {
    domain.local;
    }
    router {
    10.10.0.254;
    }
    }

    [edit]
    root@firewall# show security zones security-zone trust
    interfaces {
    fe-0/0/5.0 {
    host-inbound-traffic {
    system-services {
    dhcp;
    }
    }
    }
    }

    [edit]
    root@firewall# show interfaces fe-0/0/5
    description "Trust Interface";
    unit 0 {
    family inet {
    address 10.10.0.254/24;
    }
    }

     

    Am I missing something obvious?

    Thanks a bunch

    Interestingly, rebooting the firewall seems to have fixed this.
