2 NIC Cards, 2 ISPs: What could happen?

oblio98 · 10-12-2007, 07:29 PM

I have an ASUS MB that has 2 ethernet ports. I have been using a cable modem for my internet service at home, but I am going to try the DSL from my local phone company and see how it performs in relation to the cable. (It's about $40 a month less)

If I get the DSL and connect it to the second ethernet port (not currently used), I would assume that I have to disable one while the other is active.

What would happen if they were both active at the same time? I know that would be technically a "bridge", but would it hurt performance, or create a problem with either ISP?

Thanks

Actually, Windows would pick one to use, probably the one with the lowest interface metric. Now, if you had a dual-WAN router, you could use both of them!
