yes, this is a crazy subject. I have 4 ADSL lines to the same provider, which
even have the same gateway. Those lines are connected to the same machine (more
crazyness: even connected to the same nic. it works fine, I swear). this machine
will serve this conenction to a local net.
so, I setup the ifaces correctly, everything works. I add balancing using this
command:
# ip route replace default nexthop dev ppp0 nexthop dev ppp1 nexthop dev ppp2
nexthop dev ppp3
I try this downloading a iso image using BT and checking with iptraf. the load
gets balanced. fine.
then I issue this command to setup masquerading for each ppp line:
# for i in 1 2 3 4; do
sudo iptables -t nat -A POSTROUTING -s 172.16.16.0/22 -o ppp$i -j MASQUERADE;
done
Have you tried instead:
iptables -t nat -A POSTROUTING -s 172.16.16.0/22 -o ppp+ -j MASQUERADE
?
I do not know the implementation, but perhaps one rule with a '+' makes
a difference over summing up the 4 individual interfaces.
Interesting setup you have anyway!
