by : Hi,
: I have internal network using unregistered Class B IP address,
Hope you are using a RFC 1597 compliant addresses. If not and your
"unregistered" addresses get out on the internet it is possible that
they could create a problem for someone else.
: connected to the Internet by slip/ppp dialup connection. I've been
: trying to set up Internet firewall with two ethernet cards so that
: network traffic can only go out but can not come in except the
: Internet e-amil for WP Office e-mail, and my unregistered class B IP
: address does not get broadcasted to the internet. So far, I assigned
: registered class C IP address to first ethernet card for the incoming
: Internet traffic like e-mail and unregistered class B IP address to
: the other for the outgoing internal traffic to the Internet. But it
: doesn't work.:( I can only ping terminal server of Internet
: provider. And my e-mail isn't coming through.
Sounds like what I had happening. Did you set up default routing to
use the ethernet card that is connected to the Internet?
