3 PCs, 9 IPs

I have a network with 3PCs, and each have 3 IPs. Is there any way to
combine the bandwidth of 2 IPs, ex 2 x 10Mbit ethernet cards into 1
20Mbit connection, and have it only see 1 IPs address?

I kept the internal IPs simple:

192.168.0.10 - *.18 subnet 255.255.255.0

If so, would the same process work for external IPs? Do they have to
be on the same subnet?

Through my ISP, I have 4 IPs, 320Kbit upstream, and 3Mbit downstream.
My goal, if possible, is to combine the IPs for a total upstream:
1280Kbit downstream: 12Mbit.

Thank You,

I think most of the time, when the limitation is put in place by an isp it
is set up thatone dsl line can only carry x bps. If there are multiple IP's
on one dsl they don't each get the data rate that was advertised. They
share the bandwidth that is available.

If you are running a cable line most of the cable isp's do the same type of
limitation in the modem and this gets set when the modem is powered on.

I believe that is called bonding. Not sure if it is covered in the
Adv-Routing HOWTO (or it may explain where to find more info). One
problem is that whatever bonds on the other end would need 2 interfaces.
If you tried to connect (2) 10baseT connections to (1) 10baseT connection,
it would still only be 10mbps total (or less if on hub instead of switch).

It would either require cooperation of your ISP (for other end of
bonding), or possibly a fast enough internet host to bond.

What type of connection do you have? If it goes through 1 modem, I
suspect that your total bandwidth is no different which or how many of
your IPs you use. You would need multiple physical connections (not just
multiple IPs on one connection) to do load balancing or bonding.

Thankyou for the information. I will do some futher investigation on
this bonding to see if I can futher my knowledge.

At this time it is a DSL connection and yes the limit is per modem,
but I have 3 modems (1 modem has 2 IPs). If it is 3Mbit per modem I
should be able to snaffle a theoretical 9Mbit total if they can be
linked.

why don't you just buy a 100Mbit card? doesn't cost a fortune (you get
'em around 7€) and you don't have this problems...
