Hey pals...;)

 RTFM. Check the LARTC HOWTO on the following points:


4. Rules - routing policy database
        
        4.1. Simple source policy routing
        4.2. Routing for multiple uplinks/providers
                
                4.2.1. Split access
                4.2.2. Load balancing

J,

 What i meant is...like in Linux you make use of the two external
connections and collate them as mentioned in the document. Can you try
keeping the Linux box in front of the two windowze boxen and collate the
two LAN connections coming from them as mentioned in the HOWTO???.

[LARTC] HOW TO COMBINE 2 DSL LINES IN THE SAME COMPUTER

[Tesla 13]

Hello,

I have 2 DSL lines on the same computer that gives me 2 different IP 
addresses on different subnets.

2M/256K: PPPoA
1M/256K: Classical IP over ATM

How can I combine them (1M line and 2M line) together so that I would be 
able to use them at the same time to pull in at 3 mbits?

I tried using both connections at the same time but one line maxes out (the 
one that has the default gateway), the other is staying there idly. I added 
the kernel.org route to use second connection. I can get 3 mbits download by 
ftping to to kernel.org (1 mbit line) and other FTP servers (2 mbit line, 
default gateway). Both lines are maxed out. How to do this for all 
connections without dropping them to the routing tables (it is not possible 
to know the IP addresses of all connections since I use file sharing 
software)

I am using Windows 2000 advanced server as my computer. The DSL modem has 
drivers that work only on Windows -- no Linux support, so it must be 
connected to a windows machine. I have single DSL modem, single DSL line to 
the telco but 2 profiles on the telco that I can use simultaneously. I 
cannot connect 2 connections to different computers. Both must be on the 
same machine.

I do have linux computers working.

Does anyone have any idea how to go about this?

I am not on the list, so please respond directly to my email 
tesla1313@hotmail.com

Many thanks in advance for your time!

Jimmy

I think it would not be able to do it, since both links are not the
same speed. But please correct me. I think I am right, but I may not
be. 

It is like when you want to do trunking on switches, that means,
combine 2 or more ports on a switch to get more bw available. If the
ports were not of the same speed, that would not be possible to
achieve. And of course, all the ports must be full duplex. The
technique is to send out data on a port at a time, in a known
sequence. If ports are not the same speed, data on "x" port would
arrive first than data on "y" port, being imposible to rearrenge
packets on the other end, is it clear?

And why being full duplex? Well, for the same reason. If ports are not
full duplex, then if you sent out data on port "x" but suddenly you
are receiving data on port "y", what you had to send on port "y" will
have to wait. But in that time, data is travelling across link "x",
and data sent out on port "x" will arrive without their "parent" data
which had to be sent thru port "y". Concluding, when data sent on port
"x" arrives to the other end, data that had to be sent on port "y"
will have not arrived yet.

I hope I was clear.

You must be referring to "bonding" or "EtherChannel". I have tried it in 
linux. What you are saying can't work, becouse:
bonding, creates a seperate virtual network interface, which is the one 
with the combined speed. THIS is the one you assign your IP to. The real 
network interfaces aren't assigned any ip, they are used directly by the 
bonding driver.
What is more, this technology cannot be used for connecting a single 
computer to multiple networks. It is used to connect to another SINGLE 
device, which uses the same technology.
The only way that I know of, is using BGP on BOTH sides of a routing 
device, and set both metrics to the same value, for the default destination.
I am pretty sure that BGP is not offered by any provider here in Greece, 
except if you a corporate customer, for example buying several megabits 
of bandwidth, using a leased line.
Maybe linux's policy routing could do the task. But I haven't tried 
anything even remotely similar.
A few month I asked my Cisco instructor for that same problem. He told 
me that it CAN be done, but it SHOULDN'T be done, becouse it is not 
stable, by design.

iproute2 will do this.  There is an example in the online Policy Routing 
Book at policyrouting.org

yes, that's right .... well, I tried to say that, I was not as clear
as I tought...

well, again, that is why I think it will not work. If you want to
combine these two real adsl interfaces into one virtual interface,
you'll have to do it on the other end .... and as these lines are not
the same speed, packets will not arrive at the same time for a correct
re-arrengement.

I've never tried, thoug if you have to adsl links of same speed, on
both ends, I think it could be possibly done. I repeat, I've done this
on switches, but only switches ....
