[Opensim-users] external computers cannot login

[Pryderi]

Thanks Impalah for your very clear answer,
1) DHCP is off;
2)With xampp web server it rederects correctly to my computer, so i guess
it's correct.
3)As i wrote up, the webserver works.


Without this line:

192.168.0.2      http://pryderi.dyndns.org <http://myaddress.dyndns.org/>

in windows/system32/drivers/etc/hosts, it works only from external computer,
with that: only from internal.

And if I use the http://pryderi.dyndns.org <http://myaddress.dyndns.org/> in
a browser, without that line, of course it doesn't load.... i guess it is
this NAT loopback.
