Setting up NICs for tx or rx only

[ecgroup]

i have 2 gigabit NICs installed and I am running Fedora 13. I am using this machine for webfiltering and would like to setup the NICs so one does the Tx packets and the other handles Rx packets. Is there any way I can do this or am I dreaming?

I guess the bigger question is why do you want to do this?

[ecgroup]

Trying to minimize the redirect time. Moved from a 100Mbps NIC to a 1000Mbps NIC and found increased response through the webfilter. I just wanted to see if any lag was noticeable with once NIC using all 1000Mbps for Tx and one for Rx, since I will have about 550 users accessing the internet.

If you are placing this box in-line then you are going to have to allow both sides to rx and tx.

Machine is not in line. Is there a way to do it or are you going to dance around the subject and make no progress on my question?

Sound like you are looking for asynchronous routing which is a bad thing.
Can it be done, I think so. But you are going to have to change a lot of routing tables to get it to work.

I will just go and get help elsewhere. All I wanted was help with an problem I wanted to fix, and I got nothing from this forum. Thanks for all the non-help!!!!

[Lazydog]

It has nothing to do with not wanting to help and more to get you to understand what you are going to do and problems can arise from what you think you know. I still cannot figure out why you only want traffic to flow one direction when it should be flowing in both directions. Asynchronous routing is never a good thing and should be avoided when all possible.

And to answer the question you posted, 'or am I dreaming?' the answer is yes because of what I have said about asynchronous routing.
