hi guys out there, i'm a newbie here...

got two quite similar problems :-

1) routing problem
machine : p4 1.6, 256mb ram, 20ghb hdd, eth0, eth1
o/s : suse linux enterprise server 9
adsl router ip : 192.168.0.1/255.255.255.0

currently configured eth0 as 192.168.1.1 and link it to LAN, eth1 as 192.168.0.2 and connect it to the router. enabled dhcp & it works fine, but other pc on the LAN couldn't access the internet eventhough could access (ping) the router. what is my mistakes? HELP ME

1) routing & interface problem
machine : p4 3.0, 1gb ram, 70gb hdd, eth0, sit0
o/s : suse linux enterprise server 9
adsl router ip : 10.117.212.129/255.255.255.192

currently configured eth0 as 192.168.1.1 and link it to LAN, sit0 as 10.117.212.130 and connect it to the router. but nothing happen to sit0 (no configuration found!). what is sit0 stands for? am i have to put another ethernet adapter (eth1) to connect to the router, so the server can be a router? what should i do? HELP ME

Thanks

I'm not really an expert but i had a simmilar problem (cable modem). Is that router your ISP's router? The adsl router ip is not routable. 192.168..x.x are not routable ips. my cable modem has a simmilar ip 192.168.100.1 but it 's only used to configure the modem or see stats using http://192.168.100.1. You could try with your current config http://192.168.0.1/. Actually the router must have an ip assigned by the isp (by dhcp). All your computers cant access the web? If so i think thats your problem. Find your real router ip (the routable one). Even then i still think you need your isp toregister your macs but i'm going to far. I'm really a newbie but i had a simmilar problem, hope i helped.

thanks but it still don't solve my probs

the adsl router is mine, not the isp's.

Firstly, the sit0 interface is an internal interface used by Linux when routing IPv6 over IPv4. Unless you're using IPv6, you should run:

ip link set sit0 down
ip addr del 10.117.212.130/26

Now, on the Linux machine, you have to run

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -i eth0 -s 192.168.1.0/24 -t nat -A POSTROUTING -j MASQUERADE

Let me know if that helps. It was kind of hard to understand what you were asking for, so if you clarify I can be of more service.

thanks for the reply. so, sit0 is an internal interface, right? means i cannot use it to connect to the router? so, if i want to make the sles 9 server as an internet gateway to my entire LAN, i have to put another ethernet adapter?

router (192.168.0.1)--->eth0 (192.168.0.2/sles 9 server)
switch---------------------->eth1 (10.117.206.10/sles 9 server)
switch---------------------->LAN (10.117.206-10.117.206.50/clients)

i'm so sorry if i make you headache. i'm a newbie and this is the only place i can learn and ask for a favour. if you don't mind, you can contact me at databox3@yahoo.com. thanks

Why dont you download firestarter ......its a GUI firewall that can help you alot in your configuration download it install it disable your built in firewall first and give it a try.........I found it to be very usefull with newbies and it could easily resolve your probs

thanks a lot for the info. i'll try it someday. but what i'm thinking now, my greatest probs is with the sit0 configuration, did i?
