a software that would let me assign lan or wireless connection per application?

[kartal]

Most of us have both wireless and wired connection in our offices or homes. My problem is that I want wireless connection to be used by firefox and thunderbird and rest of my softwares should be within my wired lan. I really hate to see that some of the softwares connect to my work box with wireless while I have a wired connection between them. I changed the connection priority settings but that did not do much improvement really.

Do you know any software that would let me assign connection types to applications?

Not sure but presumably you could use a firewall to configure allowed traffic on the wired and wireless connections separately - though if you are connected to the same network with two connections on each computer I am not sure how you specify that a particular app has to access the network over one connection rather than the other ?

yes that would be my confusion as well.

The thing is that it looks like windows is checking to see which connections are available. If I disable my wireless it changes to lan right away and I get a speed boost. Otherwise somehow windows chooses wireless over wired for everything which is I hate. Because I copy files back and forth.

What happens if you block access to everything on Wifi via your firewall - do requestes automatically get rerouted via the alternative network or do you simply get blocked?

I just have windows firewall here and It is sometimes confusing to use. Do you know any firewall that can do that?

[Carol Haynes]

Not sure which would be the best for that.

Basically you need something that allows you to allow and block individual applications from sending data out of your computer.

I don't know enough about configuring firewalls - maybe someone else could chip in with some ideas. Alternatively there are other threads about firewalls where you might get some answers.

Here is one long running firewall thread http://www.donationcoder.com/forum/index.php?topic=6059.0

but there are lots of others too - just do a search on 'firewall'
