Hi all,
Well, it's seams to be a little bit more complicated than I thought to loadbalance Internat connection between 2 (different) ISP lines ...
Here is my problem:
Basically, I need to connect my office to 2 differents ISP (different gateways and different DNS ). My linux box is a 3 NICs Box. The problem is that, for the first ISP, I don't have static Addresses.
So, I would like to loadbalance, "route" and NAT all my internals Addresses
through thoses 2 ISP except for some addresses and some port numbers which will use
only the ISP2.
I would like also to detect dead gateway (maybe I ask for to much ...).
My problem is that SNAT is POSTROUTING. I am lose ... I don't know if I have to deal with iptable2 loadbalancing or if I can do this only with netfilter.
Maybe in a first part, I just would like to "statically loadbalance" my connections.
I mean, just put rules to (for example)
- route http packets to my first ISP and ssh packets to my second ISP,
- route packets from my internals IP 10.0.0.2-100 to ISP 1
- route packets from my internals IP 10.0.0.101 to ISP2
(all with NAT, of course)After, I will deal with a real loadbalancing for a part of my internal IP and
for some protocols.
Any Help will be very appreciated, Thank you in advance, Guillaume
