I have seen layer 2 devices not forwarding IPv6 packets (while forwarding I=
Pv4 packets)...
I would put a packet capture, and see if I see the RA packets coming from t=
he router.
On a Cisco router, RA is enabled by default and does not require any settin=
g.

Subject: Re: IPv6 Stateless Configuration
That's my setup right now. The problem is the machine is not configuring it=
s IPv6 address with RA already turned on. I'm guessing that the flag set on=
the UTM router advertisement messages is wrong. May I know the default fla=
gs use on a cisco router? Thanks.=20

You need all to be part of the same Ethernet network. So if this UTM can ac=
t as a bridge/switch you should be ok. Otherwise the RA broadcasts need to =
reach your device so it guesses the network and add it's Mac address to the=
network and make an ipv6 address.=20
I would say RA is a bit like DHCP in your case in terms of network topology=
but beside that RA is simpler (no leases table).=20
