fc3 networking problem


i have been working on this problem for a while. i am trying to have a FC3 box to access the internet through another FC3 box. i read a lot of articles and followed differen HOW-TO readings without getting anywhere. i even changed the way i get my internet from xdsl to modem.
the two FC3 are connected through eth cards. i set and made sure ip_forward is on. i set MASQUERADE . i modprobed the right iptable_nat module. and of course the other FC3 box gateway is set to the server eth card.
i pretty much tried different HOW-TO, my focus is whether FC3 have networking problem. is there a module or certain files need to be updated? before me now, three HOW-TO articles, pretty much the same, and nothing worked for me.
i would greatly appreciate any help. Any package installation or update suggestion, otherwise everything else is right? i

Are you connecting the 2 boxes directly through a UTP cable to their nics?
If so you will need a crossover UTP cable

the two boxes are connected directly through cross-over cable. i am able to ping anything and i was able to set-up NFS file sharing. i just couldn't set the internet sharing no matter what i did.

are you using Dual nic's? Because if they are just connected to each other, they can't go anywhere... if theres no internet connection going into one of them? Then you'd have to set up a shared connection in your network options.

NIC = Network Interface Card, aka your ethernet card... you might want to check that you CAN do that with fedora, I've never seen it done, I think someone did it with mandrake before though. If you can, then its probably really complicated to get to, make sure your not using manual ip addressing? are you using a switch, router?

i thought the word "dual" in dual nic has technical meaning.
there should be no problem with nic cards. as i mentioned, i can ping and do NFS sharing. the problem is with the internet sharing. i beleive the problem is about certain modules , missing or need updating and i don't know what is that.

I am not sure I am following what you are trying to do with the talk about masquerading, then crossover cables, then 192.168.x.x addresses only.

What I THOUGHT you were trying to do is set up a Linux box with two nics (Yes, Linux handles multiple nic's), have one nic servicing one or more local machines on an internal 192.168.x.x net and the other nic facing the internet masquerading the local machines ip addresses over to the ip address facing the internet. This shares the internet with the local net. Effectively, that Linux box is being used as a router, but obviously can be running other services as well (until consumed by bandwidth).

To do this, look through the HOWTOs for iptables.

Hope this helps...

i explained my problem at the beginning of this post. my problem is that i read and followed a few HOW-TO materials of setting-up internet sharing and did not work .
my question is now, is any body aware of FC3 networking problem, did someone actualy set-up internet sharing in fedora. is there a module need to be added or updated?
