Thanks for your response dalek

basically i have one DSL line and Dial up line connected in my Linux box.

Whatever be the traffic from LAN , wherever the link is available it has go thru that link.

i am using iptables in lin box

I found where you can use EQL for when you have two modems.  I don't see anything for ethernet, etc.  From what I have read, what little searching I have done so far, it does this automatically through the kernel.

Don't shoot me if I am wrong here.  My little 26K connection doesn't need balancing, it needs DSL attached.   :cry:

I did my searching on www.google.com/linux if you want to search some more.  There may be something Ricky would want to add though.  He more better at this sort of thing. :wink:

I did find out that EQL works with ethernet to.  This is what it said:

If you want to use 2 NICs to increase bandwidth, you have to use channel bonding - normal TCP/IP can't work this way.
For one, there is ever only one default gateway for a machine, no matter how many networks it belongs to.

You'll have to rebuild the kernel with EQL/ line bonding turned on, this allows you to make a single virtual NIC out of two.

Normal config after that.

In almost any situation, connecting 2 NICs to the same switch on the same subnet just doesn't make much sense...

there is a description in the Kernel-Documentation:
/usr/src/linux/Documentation/networking/bonding.txt


Hope that helps a bit.

I need more network experience huh?  I can google though.   :wink:  :wink:
