I have two dialup connections I use to connect to Internet. One is GPRS connection through my mobile, which is Installed as a modem on USB and the second is a CDMA phone set which is also installed as a modem on USB. If I connect both connections, windows just uses the latest connected connection.
true. everytime you connect, routing for 0.0.0.0 will be overwrite by the newly created connection.
With some very complicated tricks, you can route one type of traffic onto one modem, and a different type of traffic on the other.
(For example, web browsing on one, torrent downloading on the other.)
There's no way to use both connections for the same purpose at the same time though.
i never knew routing can be set depending on protocol. can you give me example how to do it? that would be great. if that is possible, i can browse with my office network, and download with my 3g modem.
i thought you can only set routing base on mask.
i've been using NetRouteView (http://www.nirsoft.net) at my work place. for local IP use my office network, and to go outside use my modem. lucky some guys installed proxy so i can use it to browse instead of have to browse through my modem.
how about i'm using mirc and want to use my 3G and ICQ that i want to go thru my LAN to the internet?
i power on my machine, using DHCP
private IP 10.10.10.10
route for 0.0.0.0 will go thru 10.10.10.1
then i connect my 3G modem
public IP 220.127.116.11
my windows will add another route for 0.0.0.0 to use 18.104.22.168, with exactly the same metric with 10.10.10.10
since both route has the same metric, windows now will decide by which connection is faster. unless i delete route that go thru 10.10.10.1, both irc and icq will go out thru my company route. and after i delete that route, my connection to outside world will always go thru my 3G connection.
of course i can add new route and set which way the packet should go thru depending on the IP/IP range of the destination.
now it's easy with just 2 application that connect to only 2 IPs.
how about if i want internet explorer going thru 3G and firefox thru LAN?
forget about proxy, i already talk about that in my previous post.
