As I said, it depends what you're using, so if iptables, this is what you need to do:

 

From here:

 

http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch14_:_Linux_Firewalls_Using_iptables#Masquerading_.28Many_to_One_NAT.29

 

iptables -A POSTROUTING -t nat -o eth0 -s 192.168.1.0/24 -d 0/0 -j MASQUERADE

 

assuming that eth0 is your internet connection, because you mentioned eth1 is your internal network. Replace the IP address with your internal network if it's different.

 

Check if your machines can then access the internet or simply from a machine do:

 

ping 8.8.8.8

 

and if it replies, that means it's working. Then to save it:

 

service iptables save
