Folks, I need some troubleshooting help with ipmasq.
Here is a a bit of the setup:
486 ipmasq/firewall box with 2 nics isa nics installed running redhat 5.0, eth0
goes to the internal network (192.168.1.xxx) while eth1 goes to the net via my
adsl connection (DHCP). A bunch of windows machine routed through a
multihomed Linux file server using ipforwarding are also connected to this
firewall/ipmasq box.
Just to do a quick trial I followed what I saw at
http://www.infoworld.com/cgi-bin/displayNew.pl?petrel/980406np.htm
and set the 486 ipmasq box with just a win98 client machine connected
directly to it. The 98 box has the ip address of eth0 (192.168.1.2) as its default
gateway and the 98 box is assigned 192.168.1.6
I am able to use the ip addresses to ping eth0 from the 98 box and ping the 98
box from the linux box.
Now I enter the rules below
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.1.0/24 - D 0.0.0.0/0
all the F, I, and O rules has been cleaned out previously as I was working
through the firewall setup chapter in Linux Network Toolkit by Paul G. Sery
(absolutely excellent book by the way for any new to linux folks)
this sort of works as I can ping the outside world fine from the masq machine
and ping the 98 box also. I can even ping eth1 from the 98 box by typing its
dhcp assigned address. Now the problem is that I cannot get out to the net
from the 98 box.
The /etc/hosts file on the ipmasq box lists all the names and ip's for the other
internal network machines. The name and domain of the ipmasq box are
thecomputer.thehouse.com. The hosts.sam file on the 98 box has the same
info as in the /etc/hosts file on the linux box. The 98 box is pointed towards the
linux box for DNS info (a la /etc/hosts) and the 98 box is called
win98.thehouse.com (these names are all made up, but you get the idea)
Suggestions on what I am missing here please. I suspect it is something quite
simple that I am overlooking.
TIA
Cheers
Harondel J. Sibble
