os x with public nginx web server?

having great trouble serving with nginx.

alternatively nginx serves fine to local network.

however my hosted domains are not found when using nginx

advice please.

details attached

os x 10.5.6, nginx 0.8.53
web sharing + apache on www.peepo.com resolves fine.
apache is shut down: telnet localhost 80 Connection refused

my router IP address is 81.134.22.123

http://192.168.1.62/
http://81.134.22.123
http://www.peepo.com
all resolve fine on local net,

but apparently not out in the world:
http://downforeveryoneorjustme.com/http://81.134.22.123

both report broken

nginx.conf
server {
listen 80;
server_name www.peepo.com peepo.com;

}
