How to share my internet connection to other PCs

[abailore]

Hi everybody,

My PC has internet access through broadband connection. I need to share the internet to many other PCs connected through LAN.

To give permissions to other PCs (say with IPs 192.168.0.205, 192.168.0.217), what are the required changes I need to do to squid.conf file?

You need to do NAT using your iptables firewall (and start using iptables in case you are not doing so yet).

For example, I have this in my iptables script:

#First we flush our current rules
iptables -t nat -F

#My net interfaces, this is probably the only thing you need to change
LAN=eth1
WAN=eth0

#Finally we add the rules for NAT
iptables -A FORWARD -i ${LAN} -s 192.168.0.0/255.255.0.0 -j ACCEPT
iptables -A FORWARD -i ${WAN} -d 192.168.0.0/255.255.0.0 -j ACCEPT
iptables -t nat -A POSTROUTING -o ${WAN} -j MASQUERADE

This will redirect conveniently all the traffic to or from your local network to or from the internet.

I don't know if squid will also requite some specific setup. I don't use squid myself.
