1. Redhat 5.2 subnet problems
I am using RH 5.2 Linux right out of the box
as a Firewall/Router on a P100
with 16Mb ram and 540 Hd.
running a firewall script from Hali Tower Darkover
Firewall design tool using ipfwadm,
and Tcp Wrappers.
I am masqing 2 other windowz 95 machines behind this firewall,
via a 5 port hub.
As of now I am still using an old script generated over a year ago
designed for use with 2 nic cards and it works Ok....
I am trying to figure out how to allow a 3'rd nic as a subnet, and
allow access to a NT4 Ftp and http server and make it available to the
but still keep the firewall/router secure enough to protect the
I have the routing tables working with out the ipfwadm script up and
running and all is sharing ok, but I have not tried to setup the Squid
When I disable the Firewall Script or remove the cable from the
"card to card" re: Crossover cable and connect it to the hub inside
with a "straight through" cable behind the firewall I can Map the
drives on the NT box to the other machines re: 192.168.2.10,
192.168.2.20 and see them in the Network Neighborhood in the Win95
Here is the setup:
eth0.......IP Via DHCP
eth1.......IP = 192.168.2.1 "Protected Internal Network"
eth2.......IP = 192.168.2.129 "Subnet"
the NT's card IP = 192.168.2.130
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 0.0.0.0 255.255.255.192 U 0 0 77 eth1
192.168.2.128 0.0.0.0 255.255.255.128 U 0 0 2 eth2
xx.xx.xxx.0 0.0.0.0 255.255.254.0 U 0 0 358 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
Is squid the answer to transparently redirect inquiries to the
external card, from the outside world, to the NT Server machine
through the subnet...?
Is this the most practical way to do this..?
