Hi,
the problem is with the host-inbound-traffic settings. currently you have set ssh,ping,http and https at zone level and dhcp,tftp at interface level. so for this interface fe-0/0/0 only dhcp,tftp are enabled(only the most specifics), the corresponding zone level settings won't apply. So enable ssh/ping/http/hppts under fe-0/0/0.0 interface itself instead of zone level.
security-zone untrust {
screen untrust-screen;
host-inbound-traffic {
system-services {
ssh;
ping;
http;
https;
}
}
interfaces {
fe-0/0/0.0 {
host-inbound-traffic {
system-services {
dhcp;
tftp;
}
}
}
}
}
Changes to be made -
set security zones security-zone untrust interfaces fe-0/0/0.0 host-inbound-traffic system-services ssh
set security zones security-zone untrust interfaces fe-0/0/0.0 host-inbound-traffic system-services http
set security zones security-zone untrust interfaces fe-0/0/0.0 host-inbound-traffic system-services https
set security zones security-zone untrust interfaces fe-0/0/0.0 host-inbound-traffic system-services ping
Hope this helps
