SRX

Hi.

Hope that someone cant help me here 🙂
I have an wireless Cisco WLC5508 with Cisco 2602 AP's and an SRX240 with 12.1R6.5 software.
The problem is that my wireless smartphone clients (tested on Iphone 5 and an older HTC phone) won't get an IP adresse from my DHCP server. even not over an Relay-server or an SRX JDHCP pool.
My windows PC's are getting an IP.
If i manually configure my iphone 5 with an static IP i get network connection.

instance-type virtual-router;
interface lo0.1;
interface st0.1;
interface st0.2;
interface vlan.2002;
interface vlan.3002;
routing-options {
    static {
        route 10.10.0.0/22 next-hop st0.1;
        route 10.10.15.0/24 next-hop st0.1;
        route 192.168.37.0/24 next-hop 10.254.0.1;
        route 10.100.0.0/16 next-hop 10.254.0.1;
        route 192.168.100.0/24 next-hop 10.254.0.1;
    }
    instance-import Management;
}
forwarding-options {
    dhcp-relay {
        server-group {
            Itplaneten_LAN {
                192.168.100.100;
            }
        }
        active-server-group Itplaneten_LAN;
        group Itplaneten_LAN {
            interface vlan.2002;
        }
    }
}

address-assignment {
    pool Guest {
        family inet {
            network 172.16.1.0/24;
            range Guest {
                low 172.16.1.10;
                high 172.16.1.254;
            }
            dhcp-attributes {
                grace-period 3600;
                domain-name nsc01.guest.local;
                name-server {
                    89.184.128.192;
                }
                router {
                    172.16.1.1;
                }
            }
        }
    }
}

Any one?

Kind regards

Hi Jonas,

There is a hidden command that will make this work in the JDHCP server, and it may work for you with DHCP relay as well (I have NO idea why it is hidden seeing as it stops Mac OS X, Windows CE, HTC, and numerous other DHCP clients from working):

set forwarding-options dhcp-relay group Itplaneten_LAN interface vlan.2002 overrides no-unicast-replies

 Hope that helps!
