[lug] One last question (routing and MASQ)

let me get this straight:  Your linux box has two ethernet cards.  One
(eth0) goes to the cable modem (or whatever it is) and the other
(eth1) goes to your internal network.  You have a Solaris box, an
iMac, and a Windows box on your internal network.

              Broadband
                  |
              +-------+
              | Linux |
              +-------+
                  |
        +---------+----------+
        |         |          |
   +---------+ +------+ +---------+
   | Solaris | | iMac | | Windows |
   +---------+ +------+ +---------+

If this is not a correct representation of your network, then please
draw it out for me.

Also, please send the results of the following programs on the
following boxes.

Linux box:
netstat -rn
ifconfig -a
traceroute 128.138.240.1

Solaris box:
netstat -rn
ifconfig -a
traceroute 128.138.240.1

Windows box:
route print
ping 128.138.240.1

Hopefully I can help!

JS> Thanks everyone for the helps :} with my SMTP and cable modem problems. I

JS> I have one last (if there's ever a last) problem. If someone might have
JS> the time.

JS> If I'm able to ping from iMac thru eth0 to eth1 but can't go any further-
JS> then /sbin/route is ok, as well as MASQ. So would this mean it's stopping
JS> at the firewall? Or is there something else that could cause problems. I
JS> am able to ping to and thru but not outta linux using Solaris, iMac, and
JS> Windoze. But only the linux box will make it out of it's eth0 (broadband).


JS> TIA,

JS> John
