Re(OT): Iptables action Return; Resolved 'automatic 'Static routes - Thanks

[Eric Scott <scottclansman@xxxxxxxxxxx>]

While we're talking networks... I have a linux box hooked up to a T1 as 
a web server... suposedly.  IP is 12.170.195.36, subnet 255.255.255.0. 
Internet isn't burping, in or out.  Another computer that's attatched 
to the same T1 can access the site fine, but the internet can't.  Any 
help?  Obviously I don't know much about dealing with IT setup stuff, so 
bare with me.  Is there something else I should have my DNS set to or 
something? I dunno.
    Thanx,
               ES
