My landlord shares his wireless DSL with the rest of the folks in the
house/apartment. He has an Airport router which serves up DHCP (and
receives a single dynamic IP from the provider). I am running a
webserver behind the router through dyndns.org and now I would like to
put rc.firewall in place with some good rules. The only problem is I
can only assign my ethernet card a private IP. (no sense having two
ethernet cards for this set-up)
Is there a good rc.firewall ruleset that addresses this set up? I'm
guessing this would be nearly impossible since everything is private
IP. I don't have access to his router (to replace his airport with a
linux firewall leading directly out to the provider, for example).
Unless there is some way to specify that all incoming traffic from the
gateway... but, see! I don't think so.
Any help would be appreciated. Thanks in advance to the group and to
any effort toward helping to sort this out.
