Connecting to two networks at once

[BassBomb]

Is it possible?

I have DSL and Cable line, seperate. One is wired LAN for 4 pc's the other is Wireless only.

Is it possible to have a PC connect to BOTH networks for Internet access, at the same time?

How will a program such as torrents/browser know which one to use?

My goal is to use Cable for torrents, dsl (wireless) for browsing)

No, it is Not possible.

If it was possible many dishonest people would use their neighbor Wireless and their own Internet at the same time.

Well, you can connect to and use resources on both networks at once, but your computer can only use one path out of either network, i.e. one path to the internet.

It is possible, for example by setting static routes on your machine so that different destinations will use different gateways, or by proxying through another machine and using iptables to route packets differently depending on how they are classified (eg different protocols). This is not too difficult to do.

The question was about Internet connection.

And thus the answer is No.

Put different machines on each one. Who doesn't have a handfull of computers these days? 😛

What is it with people and torrenting these days? sheesh.

The answer is yes. Consider using a linux pc using iptables as the gateway for default traffic. The "router" could easily classify all traffic flowing through it into http / https traffic and everything else. Have three interfaces on this machine, one for the internal network, and two more, one each for each internet connection. Depending on how the packet is classified, use the iptables --out-interface option to send the packets out accordingly. This is probably not the only way to accomplish this (eg this may be possible on a cisco router, I just don't know how).

If you are going to insist otherwise, please provide a better explanation for why you believe so.

You can also use a DD-WRT based router with the multi-wan script and use both. Then you just set up iptables like alpineranger stated above. You would have to make sure the router you chose has a switch that is vlan capable though. I have to agree about the torreting, I just don't get how someone would need an entire cable connections to be dedicated to it??

Also very easy with a pfsense base router.

Actually most my downloading is not done via torrents.

I think I will set up one machine on each network

Everyone above is right. For "internet" purposes - where you probably don't know the destination IP of everyplace you go or connect to - there is no easy built in way to do it.

Note I said Easy, and Built In.

My goal is to use Cable for torrents, dsl (wireless) for browsing)

Devices with Dual WAN ports - such as a lot of stuff by Hotbrick, Netgear has one, Cisco definitely, and some others will provide a single LAN connection and allow you to pick and choose the traffic going to each WAN device, provided it has a predictable port, destination IP, source IP, etc. You would need to limit the torrent ports and assign them to WAN 2, while telling the router that port 80 should go through WAN1.

It's pricy. Hotbricks start around $500 - the Netgear we use here was about $399, and the Cisco was nearly a thousand.

No one else said "Easy, and Built In" Like JackMDS says, the question is about "Internet connection" with no other qualifiers.

And as for the cost, with my suggestion, using an old spare pc, with a few extra ethernet interfaces, the cost should be minimal to none, depending on what equipment you can find lying around. With port classification, port 80 and 443 out one way, everything else out the other, you don't need to care what the destination IP is.
