Hi all,
I want to connect my LAN to the Internet over two different Connections. One is a
static E1 (2Mbit) connection with a permanent IP, the other one is a so called
DSL-Light connection (ADSL with 64kbit up and 384kbit downstream) with a dynamic IP.
The reason is that I have to pay the traffic on the E1 and the DSL is flat fee. So of
course I want to push as mush as traffic over the DSL line.
________
E1 | | Ethernet
Internet <---->| Router |<---------> LAN
<---->| |
DSL |________|
What I want to do is something like the following:
Basic model:
Because the upstream from the DSL connection is really to slow, I want to use the E1
for uplink and the DSL as downlink. (Can I do this by Masquerading with the IP of the
DSL-Line and sending over the E1, so the Answer comes back over the DSL-Line?)
Exemptions:
- Some services, like SMTP, should always use the DSL-Line as uplink.
- Some services, like HTTP or SSH, should use the E1-Line as downlink.
- And my last wish, if the DSL-Uplink is not in use, this link should be used for
sending data, until its bandwidth limit is reached, and only then traffic should be
send over the E1, too.
I know its still some days till Christmas, but I don't want to shorten my wish list
until you all tell me its not possible,.. but my problem is I don't know where to
start.
I am good at using iptables/netfilter and already used tc for setting up some QoS
rules for traffic shaping on different services,.. but I didn't do something like I
want to do now.
So I want to ask you, to give some tips what techniques / services to use, to do
something like this. How to set up the basic model and how to break it to complete my
whish list ;).
Thanks,
