</I>><i> OK, it is all looking a lot clearer now. Your router can do what you

</I>
The computers and router are connected via ethernet cables, within a
house so I assume that is considered a "same" network.

</I>
Yes, I use such as address to access the router via a web browser.

</I>><i> to disable the personal firewalls on the two Mandriva boxes.

Host is up (0.00016s latency).
MAC Address: ... (computer)
Nmap scan report for 192.168.0.3
Host is up.
Nmap done: 256 IP addresses (3 hosts up) scanned in 31.54 seconds
><i> need to look at the routing tables to make sure they are correctly

</I>><i>
</I>route command terminal output (note: personal firewall not disabled at
the time of writing):
