Hi Greg,

This is getting to be a long story, so I'll only include the essentials
from previous mails...

Okay, we have an external address (150.101.208.30) and an Internal
address (10.0.0.138). Do you have 10.0.0.138 as your default gateway on
the Mandrake box? In /etc/sysconfig/network you should have
'GATEWAY=10.0.0.138' and 'GATEWAYDEV=eth0'

Is your RedHat 8 installation running its own DHCP server? 
Do you have any messages in '/var/log/messages|grep -i dhcp' on the
Mandrake box?

Mmmmmmmmm, the way I read the -pointopoint keyword in the docs for
ifconfig, what you are doing here is attempting to set the address for
the other end of the link. Now, I haven't been following this thread
until now, so I'm not sure if you've been told specifically to use
-pointopoint, but I don't think that this is doing what you want...

Here, RH is 10.0.0.1, the gateway should be the internal address of the
router, which is 10.0.0.138.

Google tells me that NOTRAILERS means that the interface doesn't support
trailer encapsulation. Don't ask me what that means :) I don't think it
is important here, however.

Forgive me from snipping from here to the end, but I think that the main
problem here is DHCP. Your router needs to get its external address by
DHCP from your ISP, but if it is also serving DHCP to the lan, you could
have a conflict if you are also serving DHCP in Mandrake. This may not
be the case, however, but I would try the following:

Turn off dhcpd in Mandrake and let your nic get an IP address from the
DHCP server in the router, if it has one...

Otherwise, set a static IP on your nic of 10.0.0.1 and make sure that
your gateway is set to 10.0.0.138 and dev eth0.

I hope this helps,

Kind regards,

John...
