Hi Cynthia,

All the explanations given are correct but in my experience you'll lose these settings in case the server reboots, this solution works without modifying iptables, basically what you are doing is making your linux box a router.

Assuming eth0 is your WAN interface, add the following lines to /etc/rc.local

echo 1 > /proc/sys/net/ipv4/ip_forward

/sbin/route add default gw 192.168.6.1 dev eth0

Then restart your network service and run the rc.local script

OR the same principle here but you need to change SNAT ip everytime u change provider or WAN ip
iptables -t nat -A POSTROUTING -s 10.10.20/255.255.255.0 -j SNAT --to-source 192.168.6.142

Grrr ---makosa ya network address

iptables -t nat -A POSTROUTING -s 10.10.20.0/255.255.255.0 -o eth0 -j MASQUERADE

OR the same principle here but you need to change SNAT ip everytime u change provider or WAN ip
iptables -t nat -A POSTROUTING -s 10.10.20.0/255.255.255.0 -j SNAT --to-source 192.168.6.142

This is why i love shortcuts:

iptables -t nat -A POSTROUTING -s 10.10.20.0/24 -o eth0 -j MASQUERADE

OR the same principle here but you need to change SNAT ip everytime u change provider or WAN ip
iptables -t nat -A POSTROUTING -s 10.10.20.0/24 -j SNAT --to-source 192.168.6.142

Kind Regards,
Wilson./
