Multiple Network Card RH9??


I am going crazy, doesn't matter if use the ifup or the interface, but only the last card activated will work. I mean I can ping an address on that side, but only if it is the last one activated. Then the other one stops pinging anything that is on it. So I activate it, then I can ping on itm but the other one won't.


Is this some sort of bad bug in RH9?? Or something...

It is driving me plum crazy.....



Thanks in advance,
John S.

Looks like you have both cards configured with a default gateway...

Choose the card which has the internet connection and give it the default gateway setting.

OR...
You may have a conflicting ip number and/or subnet mask.

Here is the deal....

We have real IP addresses and need to keep it that way...

Our router is at xxx.xxx.xxx.254

I want the one lan at xxx.xxx.xxx.xxx with a default gateway of xxx.xxx.xxx.254

I want the second card to be on my lan at xxx.xxx.xxx.252

I had left the net masks the same. 255.255.255.0

If this is true, I think I hate linux... I have segmented my Lan's out this way for years and year on Novell and Windows.

I did try changing my subnet mask on the lan side, same results.
I left the side going to my router at 255.255.255.0 and made the lan side 255.0.0.0

I changed one other machine on the lan side to 255.0.0.0 then tried to ping it no go. Then I ifup eth0 and then I could ping it, but no longer ping my router, ran ifup eth1 thenI could ping my router, but no longer could ping the machine on the eth0 side.

UUUHHHGGG!!!!! lol

OK, I just made a dual firewall solution, and it does seem to be working...

Now on to port forwarding....
