Shorewall users - Apr 2002 - I can''t connect to the internet with Shorewall.

Hi,

I''ve installed Shorewall on Mandrake 8.1 and edited the interfaces and
hosts
file but I can''t connect to the internet with it. I can connect if I 
uninstall Shorewall.


This is from my interfaces file:

#ZONE    INTERFACE     BROADCAST      OPTIONS
net ppp0


And this is from my hosts file:

#ZONE     HOST(S)     OPTIONS
net ppp0:myip


I did not edit the zones file and the shorewall start command etc works fine 
as far as I can see.

Does someone know why I can''t connect to the internet?

Thanks,

Wayne Bornall

You shouldn''t put your own IP in the ''net'' zone.  If
you have a simple one/two
interface setup, you shouldn''t need to use the hosts file at all.  Just
the
interfaces file is enough.  Check out the one interface example at
http://www.shorewall.net/pub/shorewall/LATEST.samples/one-interface.tgz.

You may also have a problem with your policy or rules file - i can''t
say
because you haven''t said anything about them.

You may want to check out the Shoreline QuickStart Guide:

http://www.shorewall.net/shorewall_quickstart_guide.htm

That should help you get your firewall up and running quickly.

90% of all Shorewall users don''t need to modify the hosts file and 80%
of
those who try to modify it get it wrong -- count yourself among the latter
group.
