DMZ to Internal

Hi

Have been trying to get some of our DMZ servers to work with the UTM for services etc WEB proxy NTP with no luck

UTM has ..

Internal interface

External Interface

DMZ interface

and all sit behind a Juniper

DMZ hosts have access to Internal address of UTM but nothing works

FW log shows

2015:11:18-12:02:42 viper ulogd[3556]: id="2001" severity="info" sys="SecureNet" sub="packetfilter" name="Packet dropped" action="drop" fwrule="60001" initf="eth2" mark="0x315d" app="349" srcmac="58:8d:09:xx:xx:xx" dstmac="00:1e:0b:xx:xx:xx" srcip="193.xxx.xxx.xxx" dstip="10.8.xx.xx" proto="17" length="76" tos="0x00" prec="0xc0" ttl="62" srcport="123" dstport="123"

Cant think what i have missed or will it just not work ?
