ppp, vtun, multilink or eql?

Hello all
First let me thank u guys for what has been answered here, many times i
have found answers lurking the group's archive.
There i go now:
I've set a VPN between France and California, using in two linux boxes,
vtun and ppp. a 3Mb up/15Mb down DSL line in france and a 1.5Mb t1 in
the US. vtun+ppp's payload is almost unnoticeable, it just runs great.
Now i have to increase the pipe's bandwidth. Not much to do on the US
side but ask an upgrade to the ISP to a 10 or greater line.
It's more complicated on the French side : multiple 3Mb/15Mb DSL lines
are way less expensive (like 40x less, such dsl lines are just
30EUR/month) than one unique fast line.
Thus i have to find a solution to make the vpn use multiple lines.

I googled and found :
I could use up to 8 serial lines (here it would be my vtuned ppps) and
then merge them using EQL. It looks like i will probably use 2 or 3 lines.
I've also read a couple of things regarding ppp's "multilink" option.

Are both solutions possible?
Is there one better than the other?

Any help Appreciated!

PS: i'm trying right now the EQL thing, but it happens that i have to
bond ( a-la eth channel bonding ifenslave) ppp interfaces with the
eql_enslave command which happens to be missing in my SuSE 9.2 boxes.
The eql sources' url is b0rked too...

It's just plain simple to use multilink with ppp in vtun : just put it
as a ppp option in every tunnel's description in vtund conf and voilà!
ex :

ppptunel1 {
passwd <snip>;
compress zlib:9;
encrypt yes;
up {
# Connection is Up (established)
ppp "192.168.22.155:192.168.22.208 multilink";
};

}

ppptunnel2 {
passwd <snip>;
compress zlib:9;
encrypt yes;
up {
# Connection is Up (established)
ppp "192.168.22.156:192.168.22.209 multilink";
};
}


I launch the two vtun tunnels using two different dsl boxes,
the second ppp vtun just merges into the first one. It runs perfectly,
though i still have to run a proper bandwidth test to definitely
validate it.
It seems too that multilink ppp is more up-to-date than EQL, which i
haven't found a non broken url to download the sources from, i wonder if
it's deprecated...

However, i've found a _minor_ catch in my setup :
if there's no traffic, the ppp terminates saying :
pppd[934]: Terminating connection due to lack of activity

It doesn't break anything really because vtun is launched with the -p
(persistent) flag that reconnects the tunnel after termination. I'm not
even sure it would improve the link's stability to remove this behaviour
as it is in some way a good "dead link" detector...

Any clues?



thanks in advance

You likely have the pppd "idle" option specified somewhere in your
configuration. If that's not what you want, then remove it.

Hi!!

I want to know if that is possible with PPP Multilink:

Y have a pc with 2 routers in my house, DSL 2 mbps lines for example. I take 2 vpn tunnels to a host in a datacenter, one by each router. So I have 2 ways to reach that server.

Is possible to configure ppp multlink to make a wget form kernel.org from that host (or internet putting ppp0 as default gw) at 3,5-4 mbps? I want to real aggregate that 2 links

I try vtun+ppp with no luck... the bandwith doesn´t increase... i will try openvpn tap+pppoe+ppp-multilink...

Thanks and sorry for my english
