Greetings friends
I hope I explain this correctly, Please try and help me here, I am seriously
stuck
I have two interfaces on a linux router {int} {ext}
I have two PCs on either side of the router {chad} on {int} and {xxx}on {ext}
{xxx} is my gw to the net, but {chad} needs to be the only PC that can access
the internet fron the {int} side.
The problem I am faced with is how do I do it, Here is what I have got so far:
pt="/usr/sbin/iptables"
ext="eth0"
int="bond0"
chad="192.168.2.5"
etel="196.25.100.28"
#Enable IP Forwarding
echo "1" >> /proc/sys/net/ipv4/ip_forward
#Clear All Tables
${ipt} -t filter -F
${ipt} -t nat -F
## allow all from local interfaces [localhost]
${ipt} -t filter -A INPUT -s 127.0.0.1 -j ACCEPT
##Allow {chad} to etel internet direct
${ipt} -t nat -A POSTROUTING -o ${ext} -s ${chad} -d ${etel} -p tcp -m tcp
--dport 80 --state NEW,ESTABLISHED,RELATED -j ACCEPT
${ipt} -t filter -A FORWARD -p tcp -m tcp -s ${chad} -d ${etel} -o ${ext}
--dport 80 -j MASQUERADE
Please could someone help me with a simpler rule?
