Re: Networking - dhcp-client

I am not anything like an expert but maybe establishing a second DHCP
server on the Smoothwall to assign internal addresses may work better -
you may need to disable the modem dhcp server to do this and just
assign an IP address to the Smoothwall manually.
Clive, you certainly get me thinking.
Let us review what I already have:
A cable comes into my house and a surfboard cable modem is attached to
the end. It has it's own DHCP server to negotiate a lease with
whatever I hang off the end of it.
The modem used to be attached to my mandrake/win98 PC (avocet) and the
MAC is registered with Blueyonder so that the Surfboard will play > ball.
I then decided to build a Smoothwall server so that I would have a
robust firewall and also a router. Obviously I had to register the MAC
of the outward facing card in the Smoothwall server as this would now
be connected to the Surfboard and I connected a 9 port hub to the
inward facing NIC to accomodate avocet and teal.
The above solution worked flawlessly, with one small ommission - teal
would not co-operate (dunce - win95 on the same box works fine).
or: Can you not manually assign an IP address to Teal (on the Debian
side). Assuming that your DHCP server assigns numbers in the range
192.168.1.10 to 255, just pick a number that is not assigned and
manually assign it to teal with something like
"ifconfig eth0 18.104.22.168 netmask 255.255.255.0" where 25 is an
If I can't crack this teal network problem by trying to fix the dhcp
client side (which has to be the problem because ever other
combination works) then I have the following options:
Our Vigor also acts as the DHCP server and assigns addresses on the
network - the static address is to the outside world.
Obtain some Woody CDs and then try again with a revitalised teal
Try plugging the cable directly into teal to see if the dhcp client
will talk directly to the surfboard so that I can upgrade to Woody
Try setting up static IPs on the network and see if I can get
Smoothwall to do the client side stuff with the surfboard - this is
new territory for me (as is most of it) and I am not sure whether I'll
also need to look at IP masquerading as well?
Now if I understand you correctly wouldn't my last option be doing the
same as your vigor 2200 i.e. connect to cable and act as a router?
In summary, I believe the chain of connections should be:
Cable Modem to Smoothwall (DHCP) server (assigning IP addresses to the
PC's on the local network) to your hub/switch to individual PC's each
of which obtains its IP address from the DHCP server or if that fails
assign an address manually to Teal.
I hope that this is not too confusing ('cos I think I'm now confused
Keep at it ;-)
