Hi, I'm trying to do some load balancing with four ppp connections. Here is what i have: a LAN connected to a redhat box which has four ppp interfaces. All the boxes in the LAN are accesing internet through the ppp interfaces in the redhat box. I'm using iproute2, in my redhat box, to setup the the four ppp interfaces as my default out going route (as described in LART http://lartc.org/howto/index.html) and I'm using iptables to masquerade all the traffic comming from the LAN. My setup is working fine, ie. my LAN can access the net throught the four ppp interfaces. My problem is that i don't know how is the load balancing working. Some times one of the ppp interfaces is used more than the others (and that is my problem). According to LART the routes are cached, can someone go a bit into more details in this caching thing??? how does it work? which particular files in the kernel are doing this? I would like to implement a simple round robing algorithm (with no caching) for doing the laod balancing. That is first connection established gose through ppp0, the second connection on ppp1 and so on. I could hack iproute2 and/or iptables, but i'm not sure about which particular files i should hack in order to implement this round robin algorithm. I actually don't know if what i want makes any sense Any ideas or pointers are all very well appreaciated. Thanx to all X
