[Gllug] Setting up SW firewall (Was Sharing NTL broadband using weedless router)

Thanks for everyones help.  For reasons to convoluted to go into the
other person has decided not to share there connection so I am getting
my own.  For equally convoluted reason I am using the aforementioned
Netgear router elsewhere.

Therefore the NTL box is going to be initially connected straight to
the Debian Box (I will authenticate using windowz).  What I want to know
is the easiest way of setting up a firewall no this box (preferably with
snort).  I think I can filter between eth0:0 and eth0:1 but am not too
sure how to set this up and what firewall (debian) package to use.  Is
there one with sensible preset rules set up and a web (webmin)

As a (possible) point of interest I found quite a good support forum
with various NTL support bods giving unofficial support for things NTL
do not officially support (http://www.chetnet.co.uk/portal/forum/).

 They recommend a linksys wireless router (802.11b) which is only
£36.62 inc val + delivery

There is also a similar 802.11g router which is almost certainly also a
good one to use
for £58.62.

I belive these both have detachable antennas.

If it is a DG834G then you can accomplish this by opening up the
shell mode
(see  my earlier email - 20040426120705.00f812a2.gllug at amias.org.uk )
and just set the route to the NTL box IP from the command line .

something like this should do the job .

# route del default
# route add default ip.of.ntl.box

This should hand out the right route to all dhcp clients connecting
you do this and should last untill the router is rebooted.
