I had a linux slackware machine sharing the internet in my network. Last weekend the there was a power failure and my computer had to restart.

The problem is that most of my configurations are gone.

I have
eth0: 192.168.2.104 (local)
gateway: 192.168.2.1
eth1: 10.0.0.151 (xdsl)
gateway: 10.0.0.138

I can't get my iptables, ipchains, masquerading or whatever to work anymore.

Sounds like you had data loss. Do you have a back up? If not, I would backup all the stuff that you would like to keep and re-install. Also us a journalizing file system like ext3 or reiserfs. They are more reliable when you have a hard reboot.

It isn't data loss.

The problem is that the configurations i made then where not saved in any batch file so when the system restarted i lost all those config's.

I was stupid enough to not write it down so i an desparetly searching the net for that manual that worked for me (haven't found it yet).

Now i'm asking you guys to help me out with reconfiguring.

This is just your iptables config? Did you enter all the commands manually? If so, you could log on and hit the up arrow. Your last 200 (?) command are recored. If not, I thing that you are out of luck.

I did a lot more on my computer after my configuration than 200 commands so that's not an option.

Doesn't anybody know what the commands are configure my computer again.

i got it to work on the most wierd option i could ever think off.

it's like this:

I have a router with 4 ports and a wan port
I have a xdsl modem.

What i did was putting all my computers on the ethernet ports plus the modem (and not on the wan port). So the router sees the moden as a computer.

The router suddenly started acting like a switch and didn't give any more dhcp's

All the configuration comes from the moden including the dhcp.
I can't even reach the modem config screen.

This shouldn't be possible normally right!!

But what the hell it works.
