internet sharing lost after update Suse 9.2
I have an (old) Mandrake 9.2 pc which connects through an ADSL router (192.168.100.100) to the internet.
This machine has always shared the internet over it's second NIC (eth1 - static 192.168.100.50) with the Suse 9.2 pc.
The Mandrake get's it's IP from the router through dhcp on it's eth0.
After updating Suse 9.2 (with Yast) two weeks ago I can now only use http (surf with Mozilla).
FTP, receiving/sending email, streaming music (mplayer plugin), the d4x downloader and You (yast update) do not work anymore.
Fish works as usual so I can still connect to the Mandrake pc.
The Suse machine has static IP 192.168.100.51 on eth0
How can I put everything ( ? manually) back to normal.
Re: internet sharing lost after update Suse 9.2
Have I got your network figured out correctly?
Thanks for wanting to help me out
The first setup is correct
Suse (childrens Pc) is connected to the Mandrake (my pc) which connects through the adsl router to the internet
I dropped the firewalls on both machines for testing but this makes no difference
The proxy setting on the suse is http://192.168.100.50:80
Is there a command to see why only http works ?
This is very strange - I've been using both distro's since Suse 6.4 and never experienced any problems.
Is the mandrake serving as a http-proxy? If that is the case:
This smells like a routing problem. You should set up mandrake to masquerade (NAT) instead.
HTTP is working because the proxy (mandrake?) will do the surfing for you and return the pages. Maybe your old suse was setup to use mandrake as a proxy for everything?
The other stuff (ftp etc..) is obviously not using the proxy. If Mandrake is not translating addresses, your router will have no way of knowing how to pass reply packets back to your suse box. If you do use translation on mandrake, the router will simply pass the packets to mandrake which in turn will forward the packets to suse.
If you set up ethereal and sniff the packets on your mandrake box you should see suse packets going out to the router but no return packets is coming back.
I realize this stuff is difficult to grasp without knowing a fair bit of TCP/IP. Let me know if you need futher explanation.
how do i make NAT work ?
if been through the Mandrake control center but didn't find it
You were right - it was a routing problem which I could fix.
Thanks a lot for your help !!!!!!!!
