Hi,
for the IP masquerading,
I have done it before
dia jalan cantek
I made a documentation on it
saya gunakan account tmnet dan linux box yang jadi gateway saya set dhcp
containing
address range yang boleh ditukar
saya gunakan 192.168.1.x
no need to set ip address or proxy on worksatition or client
let them get the ip automatically
here is the document
anyone pls correct any mistake or inform me if that does not work well
happy trying
To set up 'cyber cafe' environment with linux as the LAN server
Requirement
1- One linux box 2-2-x, with NIC and modem
2- A hub
3- 1 or more workstation
First, setup internet connection using (I recommend) kppp, mine connecting
to TMNET. Next, make sure your network configuration is correct under netcfg
For reference, here is the content of my /etc/resolv.conf
before connected
search
nameserver 202.188.0.133
nameserver 202.188.1.5
and after connected
domain tm.net.my #kppp temp entry
search
nameserver 202.188.1.133
nameserver 202.188.1.5
nameserver 202.188.0.133 #kppp temp entry
nameserver 202.188.1.5 #kppp temp entry
Second, set your linux box to run dhcp service
create & edit a file /etc/dhcpd.conf
my sample:
subnet 192.168.1.0 netmask 255.255.255.0{
range 192.168.1.10 192.168.1.250;
default-lease-time 86400;
max-lease-time 259200;
option routers 192.168.1.1;
option domain-name-servers 202.188.0.133;
option domain.name.servers 202.188.1.5;
option domain-name ^�tm.net.my^�
}
then create an empty file for dhcpd to keep record of what ip given to who
by
touch /etc/dhcpd.leases
next add line into /etc/rc.d/rc.local
/sbin/route add ^�host 255.255.255.255 dev eth0
reboot linux, linux should become dhcp server already.
Third, Setting up masquerading itself
Create and edit file /etc/rc.d/rc.firewall
/sbin/depmod ^�a
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_raudio
/sbin/modprobe ip_masq_irc
echo ^�1^� > /proc/sys/net/ipv4/ip_forward
echo ^�1^� > /proc/sys/net/ipv4/ip_dynaddr
/sbin/ipchains ^�M ^�S 7200 10 160
/sbin/ipchains ^�P forward DENY
/sbin/ipchains ^�A forward ^�s 192.168.1.0/24 ^�j MASQ
you can get more info on this from
http://members.xoom.com/daung/ipmasq.htm
then make the file executable by
chmod 755 /etc/rc.d/rc.firewall
next add a line /etc/rc.d/rc.local
/etc/rc.d/rc.firewall
reboot the linux and connect your client to use dhcp ip and connect linux to
isp and your client should be able to connect to internet already

hi,
I have a linux system, redhat 6.1
and have all my networking setup, and is working.
But, I can't make something like, when I online,
all my workstation online.
My workstation have set their proxy as 100.0.0.1:80, which is my server ip
address, but that ip brings them to apache webpage.
I have heard from irc says that this need ip-masquerading, izzit ?
Could any one please teach me how to setup a thing like this ?
(just same as cyber-cafe)
Thank !!
