Hi,
We have a 256 kbits/s (kilobits per second) link to the internet. it is a
router running Linux that belongs to our ISP. They have given us 8 internet
ips. (i.e- subnet is 255.255.255.248). one has been given to this router. I
have given another internet ip to the firewall running CentOS 4.5. iptables
is running on it. And also, I have installed iproute2 pkg as well.
pls see below for installed pkgs.
[root@firebox ~]# rpm -qa |grep iptables
iptables-1.2.11-3.1.RHEL4
[root@firebox ~]# rpm -qa |grep iproute
iproute-2.6.9-3.EL4.3.centos4
This firewall has 3 ethernet cards at the moment. one is connected to
router. one is connected to our DMZ zone. one is connected to LAN1.
These are ips of the firewall.
eth0 (internet) - 1.2.3.4/255.255.255.248 (pls assume it. For security
reason, I will not give you the actual ip)
eth1 (DMZ Zone) - 192.168.100.254/255.255.255.0
eth2 (LAN1) - 192.168.101.254/255.255.255.0
Now, everyone in LAN1 has access to internet. (due to SNAT rule)
Now, I want to install another ethernet card to this firewall. then, it
would be eth3.
eth3 will be as follows.
eth3 (LAN2) - 192.168.102.254/255.255.255.0
Now, I want put about 5 people (5 PCs) behind this LAN2 and give internet
access to them. But, I do not want them to use my whole bandwidth (i.e - 256
kbit/s), But Instead, I want peple behind this LAN2 to allocate 64
kbits/s(kilo bits per second) for their
internert access.
Is it possible to acheive this task on firewall running iptables and
iproute2 (CentOS 4.5) ?
If so, How can I do such thing?
If I do such thing, what will happen to the people behind LAN1 ? Will they
get whole 256 kbits/s as before or will they get 256 kbit/s - 64 kbit/s for
their internet access?
Hope to hear form you.
