Hello i need to to NAT with DNAT and i think SNAT too.
this is my lan (attached to a file)
this is my situation
Server Linux running RedHat 9 shrike
with this configuration
eth0 (two aliases)
eth0:0 IP: 192.168.0.1
eth0:1 IP: 192.168.1.1
eth1 IP: 10.0.0.1
ppp0 PPPoE used over eth1 to connect linux server to internet
eth0 IP: 192.168.1.100; 192.168.1.101; 192.168.1.102
LAN: subnet: 192.168.0.0/24
so i want to do NAT over my LAN, it means a client wich ip is
192.168.0.65 for example could have full acces to internet
but all incoming packets comes from ppp0 at theses ports 27015 27016
27017 and port 80 have to DNAT to 192.168.1.100 ip address and i guess
SNAT too, to my W2k server
i don't know how to do the script to make it possible, could you lend
me a hand please.-

Re: Iptables and Script to make it possible (Help me please)
I just had to learn this too. What helped me was the docs here ->
They have alot of howto's. The one on NAT should work for you nicely, if you
already know shell scripting. If not, it's not hard to learn either. You only
need basic shell constructs to make an effective firewall/NAT'er.
