[gentoo-user] Re: Trying to install a cable modem connection.

[Jeff Cranmer]

I figured out what the problem was.
I hadn't changed the interfaces file in shorewall to point to eth1
instead of ppp0 (the old adsl connection).  Shorewall was blocking the
connection.  Once I corrected this, I was up and running :-)

Thanks

        A good starting point may be taking a look at the kernel IP
        routing
        table -- that's what "route" is for. You probably want to use
        its "-n"
        switch to disable host name lookups.
        
        You want a route with destination 0.0.0.0, genmask 0.0.0.0
        (means CIDR
        network 0/0, or "default" upstream) and gateway somewhere in the
        range
        24.88.247.x (24.88.247/24), going through (iface) eth1. Without
        it,
        your system will not be able to talk to anything outside of your
        little corner of Road Runner's network.
        
        If you have such a route, then running traceroute (also with
        "-n")
        towards a known valid IP address should give you some clue as to
        where
        the problem is. You may also want to look at any iptables rule
        sets
        you may have; that's "iptables -L -n" (list, numerical).
        
        If you can connect to an IP address but not using a DNS name,
        that
        leaves just name resolution (/etc/resolv.conf
        and /etc/nsswitch.conf
        under "hosts:", as I recall).
