Is there any possibility to use both connections as a single line?
Like eth0-speed + eth0:anet-speed = usable speed. If not is there any
way to use one connection for bittorrent downloads (I'm using Azureus)
and the other one for browsing (Firefox)?
I am using similar setup @home. All you have to do is add somewhere
following command:
# ip route add default scope global \
nexthop via 85.x.x.45 dev eth0 weight 2 \
nexthop via 10.1.5.224 dev eth0 weight 1
In this example I am asuming that first line is twice as fast as second,
so we want 2/3 of connections to go through it, and remaining 1/3
through second one.
Please adjust according to your bandwidths.
Now, this is not really "using both connections as a single line" but is
"using both connections at the same time". This works GREAT with azureus,
because it makes/receives many connections which are not very fast each,
but aggregated you get full speed of both lines (well at least if there
is enough seeders/peers).
Problem with this setup is that if your bandwidths are very different,
it will happen from time to time that you will start a large download,
and that connection will, in some random order, go through you slower
line. In that case, it sometimes helps to flush your routing table like
this:
# ip route delete default
# ip route flush cache
and then rerun previous "ip route add..." command.
You could also create a script to do all of that automaticaly...
