You can get by with just one real IP address. Here is my notes.
IP Masquerade/Routing and DHCP
This is my version of howto setup the hardware. I have two identical NICs
that are Linux friendly. It will save you time later. I used Mandrake 5.3
instead of Red Hat 5.2. Red Hat has no problem seeing my 3C905B but it only
run at 10mb. Seem like it probe for the card, found it and try at lower
speed first and it stopped instead of try it for 100mb. Mandrake will set
the card to 100mbit and will operate at that speed.
I had both of the card on the machine. Make sure that there is no IRQ and
I/O address conflict on your hardware before you start to install Linux. It
would be nice to have video card that Linux friendly. I used X to config
the networking part later and I don't know how to do it without X. Once the
hardware is in place you can proceed the Linux installation. I usually tell
it to install everything and peel off what I don't need later. Make sure
that you label your network cable so you know which cable is internet and
which is local. The installation will only config one of the NIC. I
connect this NIC (eth0) to the internet. I used static IP for my internet
address. Let say I have a real address and it is 206.81.194.33. Input your
information for this NIC (hostname, IP address DNS and etc.). After it's
all done you should be able to ping or www to the sites on the net.
Start X and run /usr/bin/netcfg and click on the "Interface" button. You
should see the lo, eth0 and eth1. Highlight eth1 and click on "Edit". I
setup my internal IP to 192.168.1.1, mask 255.255.255.0, check on "Activate
interface at boot time" and "Interface configuration protocol" = none.
Click on "Done" and save the configuration. Then click on the "Routing"
button. Check on "Network Packet Forwarding" and click on "Save" button.
Add the following lines to /etc/rc.d/rc.local.
> echo "Start IP Masquerate and Routing"
> ipfwadm -F -p deny
> ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0
Next step is to setup a DHCP server on the local side so you can plug a
machine on this side without having to deal with reconfig the client
machine. Create a file
/etc/dhcpd.conf with the content below.
# Change acme.com to your domain name and change your IP address to fit your
environment.
server-identifier 192.168.1.1;
server-identifier 206.81.194.33;
option domain-name "acme.com";
option domain-name-servers acme.com;
subnet 206.81.194.0 netmask 255.255.255.0 { }
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.100;
option domain-name "acme.com";
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
default-lease-time 3600;
max-lease-time 7200;
}
Add the following lines to /etc/rc.d/rc.local.
> echo "Start DHCP setup"
> /usr/sbin/dhcpd -cf /etc/dhcpd.conf
> /sbin/route add -host 255.255.255.255 dev eth1
Then create a blank file /etc/dhcpd.leases. This will setup a DHCP server
on the local side. If you want to set up DHCP on the internet side you need
to add more info inside the {} for subnet 206.81.194.0 netmask 255.255.255.0
{} side. Reboot your machine and hopfully it should work.
Now you can test your setup by plug a machine on the local side (eth1). You
can have a DHCP server running on the 192.168.1.0 network as described above
so you don't have to hard code the test machine. Or you have to assign a
static IP. I set the default gateway on the test machine to 192.168.1.1
(this is important) and the IP address of the test machine to 192.168.1.2
(if you do not have DHCP setup). Hopfully your test machine can see the
internet. Email me if you run into any problem or have some good idea.

Do you have python installed, I think the py extension indicates a
python file. I'm new and learning too, but I think python is a
scripting language like perl and is used program dialog boxes and uses
other widget things (whatever the heck they are).
I'd start with selecting to install python from the rh distro.

Subject: PPP question
Date: Sun, 20 Jun 1999 04:59:25 -0700
I am a new user to Linux, using Redhat 5.2. I followed the instructions at
http://www.ftrend.com.my/linux based on an answer to an earlier question to
this newsgroup (thank you!).
I can use Minicom to dial my ISP. However, when I execute my ppp-on script,
nothing happens (I don't hear the modem "click" on). The following appears
in my /var/log/messages:
Jun 20 04:41:55 localhost kernel: PPP line discipline registered.
Jun 20 04:41:55 localhost kernel: registered device ppp0
Jun 20 04:41:55 localhost pppd[774]: pppd 2.3.5 started by root, uid 0
Jun 20 04:41:56 localhost pppd[774]: Serial connection established.
Jun 20 04:41:57 localhost pppd[774]: Using interface ppp0
Jun 20 04:41:57 localhost pppd[774]: Connect: ppp0 <--> /dev/modem
Jun 20 04:41:57 localhost pppd[774]: Serial line is looped back.
Jun 20 04:41:57 localhost pppd[774]: Connection terminated.
Does this point to anything? What does "Serial line is looped back" mean?
If anyone has an answer, please let me know in *simple* terms (this is my
fifth day with Linux).
Thank you!

Just setting the 'Password Encryption' to 'yes' isn't enough. Have you

Subject: multiple DNames per 1 ip address
Hello, I am in a dilemma,
I've been promoting linux as perfect solution for local .orgs etc. and
now am "given" an IP address with server to prove it's ability. Need
help finding answers to following question ASAP:
Where can I find out how to set-up DNS for multiple domains (such as
domain1.org, domain2.org et cetera) going to one ip number?
Machine is running RH 6.0+updates.
Is the configuration in Bind, or Apache? Or do I add a CGI/Perl routine
or? Is there a specific phrase that refers to this process?
I know how to set-up dns master for one d-name per ip address-number,
and have read O'reilly's DNS + BIND etc., but still unclear about procedure/protocol...
Your help is greatly appreciated.

Hello,
I am looking for a 10/100 pcmcia card for Linux that is capable of
>=45Mbit/s full duplex thruput.
We're sending someone to the US, with a Laptop (Dell Latitude),
where he'll be testing a T3 satellite link. We need solid performance
from the pcmcia 10/100 card, in order to be able to creat streams of at
least 45Mbit/s (both ways).
Does anyone have good experience with such a pcmcia card, and did
you test the card under such conditions ?

I'm not sure but I think your WinProxy software might use a form of
resource sharing called SOCKS, which is different from IP-masquerading.
I know that the Wingate software uses SOCKS.

AFAIK you can use ipfw to do transparent proxying my redirecting all

perhaps you are not specifying the defaultroute option when you run pppd
?
if you specify this option then pppd will make the default route thru
the ppp interface it just set up.

Subject: Routing problem with 5 NIC's !
Date: 20 Jun 1999 13:35:00 GMT
Hi,
Let me explain from the beginning:
I have a Linux box with 4 PCI NIC acting like a router to 4 sub-nets
(say 192.168.23.0, 192.168.24.0, 192.168.26.0 and 192.168.27.0). Below you
can see how it's working now (I cut out 192.168 part to abreviate):
ISP
Router ------------------------ hub ------
(26.254) optical fiber |
| (26.1)
Linux (Slack 3.7 / Kernel 2.0.36)
(23.254)| (24.1)| (27.254)|
| | |
hub hub hub
I think will be better if I add one more NIC connected directly to the
optical fiber and put the 26.1 card working only like a gateway to 26.0
subnet (isolating this subnet of traffic generated from the others 3
subnets going out across optical fiber link). Well, a tried to do that,
but since I don't have any empty PCI slot I put a ISA NIC. I had no
problemas recognizing and setting up this 5 cards (loading ne2k-pci
module first and then loading ne module). Then I setup the routes:
route add -net 192.168.23.0 broadcast 255.255.255.0 eth0 (23.254 card)
route add -net 192.168.24.0 broadcast 255.255.255.0 eth1 (24.1 card)
route add -net 192.168.26.0 broadcast 255.255.255.0 eth2 (26.1 card)
route add -net 192.168.27.0 broadcast 255.255.255.0 eth3 (27.254 card)
the very same routes in the previous setting. eth4 (ip # 26.5) got the
fiber and I replace the previous default route by the following 2 routes:
route add -host 192.168.26.254 eth4
route add default gw 150.164.26.254 metric 1
Sounds good, doesn't ? Once logged into the Linux box I can ping any
machine in any subnet ( including 26.254 ) and from there I had normal
access to Internet. BUT, from any machine in any subnet ( to say the
truth, I really don't tried all machines, but one in each subnet ...), I
cannot get out to Internet. However, any of this machines receive response
when pinging the 26.5 card... Any clues ? To me the only reason could be
the mixing of PCI and ISA cards. Before you ask, all PCI cards are Realtek
8029 and the ISA I really cannot remember now :)
Thanks,
Andre Minelli

If you're having trouble connecting to earthlink thru linux, check the

I thought that the total length of thinnet (coax) was 500m (hence the
reason it is used for longer runs)
A twisted pair can only be 100m between hub and computer (90m cat 5 + 10m
patch)
With Thicknet (AUI) having a total length of 1500m and fibers are something
like 20km without a repeater

Doesn't hotmail support pop3 connections? If so, you could have a solution,
running fetchmail to get your pop mail (delivered to your local mailserver)
