Default Multiple Network connections

Hi All,
my problem is: I need for a project stuffs, to be able to use simultaneously
two network connections at the same time, in particular one connection
obtained via a 3G Vofadone connect card to a private network and another
connection via the LAN access to the internet.
There is a solution in order to have both connections active at the same
time and using one for check email (example) and another to browse on the
internet (example) ???
Thanks in advance for your support on this topic.
Regards,
Antonio.

Antonio,

The static route table, with properly defined network interfaces and subnets,
should make this possible.

It's tricky when you want to make one interface provide backup to another (if
one connection isn't working use the other), but if you have two separate
networks, well defined, it's trivial.

Cheers,
Chuck

Default Multiple Network connections

I have a similar need and perhaps not enough networking experience to pull it
off. I have 2 computers hooked up to an ISDN LAN Modem. The modem acts as a
router and an internet connection for an ISDN connection. I live in a rural
area and wanted to add a 'broader' band connection so I have recently bought
a satellite dish for the sole purpose of getting a high bandwidth connection.
My hope was to be able to retain the low latency ISDN connection for gaming
purposes but also be able to choose to connect through the always on
satellite dish when I had a large download required or to just surf without
zapping bandwidth from my wife playing on the second machine.

So Chuck, if you are still listening, you say that if two networks are well
defined then it is trivial to be able to switch between multiple (non-dial
up) connections. Does that mean that I should put a second network card in
each machine and buy a new router and set up two unique networks? That way I
can hook up the satellite connection to one router/network and keep the ISDN
LAN modem configuration unchanged. And then simply choose one or the other
network depending on my current need? Is that the best and/or only way to
achieve my objective?

I had hoped that I could just plug 'em all together through my existing
router and then find a way via software to select which internet connection
to use in any given session from any given machine. Or in the worst case
just buy a second router that doesn't have the baggage of the ISDN modem
internal to it and connect the two routers together in some way and again
find a software solution to choosing which non-dialup connection to use on
any given session. Forgive my naivete but I am new to networking and may
have bit off more than I can chew. Is my goal a hopeless one? Thanks in
advance for any and all help and advice that can be provided.

Default Multiple Network connections

Don't think I can edit my own post, so I'll reply. Although I didn't get a
reply to my questions, I figured I'd close down my own question here before I
move on. I found a solution. I used a Dual WAN Router to manage my
connection. I can practically make any application use one or the other
connection at will. I basically run the software on one connection and snif
packets to figure out which IPs are used by the software. Then I instruct
the Router to route all packets to/from those IPS through the desired
connection. I then tell the router to send everything else that I haven't
specified through the non-metered high bandwidth satellite. This is
awesome... the discovery of the dual WAN router really made my system work
the way I wanted.

Not sure that I will check back at these forums again... at least not for a
while. Hope my departing remarks are useful.
