Dear All netfilter users and developpers,
This software is an amazing software, We are are very happy of this solution for our office.
Now, I need some help to improve our network:
Our office is based in Vietnam, and in this country (for the moment) all internet connections are unstable.
We currently use an ISP with a (slow) connection, but providing real static IP address (6). We want to add a second ISP to our office with non static IP Address. They provide us also a modem/router for NAT.
We already install a GNU/Debian Router with netfiler support (2.6 kernel) in order to manage our first ISP link.
We would like to add a network card in this router and "loadbalance" our internet connection between those two ISPs.
The problem is that some of our internal IP need to be link to a real external IP on the first provider only (For VPN connections).
Is it possible with netfilter to link some internal IP to a "load balancing" between 2 ISPs and some other on just one of those ISP ?
Is there a possibility to detect a "down" line and to use automatically the second line for all our internals IP ?
How can I manage the differents bandwith with "load balancing" ( I mean, my first ISP average is something around 64 kbps and my second is 512 kpbs: How can I said to net filter 20% on this line and 80% on this line)
Is there How to or Dosumentation for this on 2.6 kernel ?
Thank you in advance for your help,
Guillaume
