there is only one nic
Napp.it 0.8 used "old style config" with ifconfig and file-based settings.
0.9 uses ipadm similar to http://wiki.openindiana.org/oi/Static+IP that works on a default config.
You may try at CLI
svcadm disable svc:/network/physical:nwam
svcadm enable svc:/network/physical:default
# check for interface name
dladm show-link
# delete old interface (ex interface e1000g0)
dladm delete-if e1000g0
#create interface
ipadm create-if e1000g0
# add IP address
ipadm create-addr -T static -a 192.168.0.1/24 e1000g0/v4
# now set gateway and DNS ex
route -p add default 192.168.0.254
echo 'nameserver 8.8.8.8' >> /etc/resolv.conf
cp /etc/nsswitch.dns /etc/nsswitch.conf
(these are the steps done with 0.9)
