Hi all, >From the following website: http://lartc.org/howto/lartc.rpdb.multiple-links.html I find the following intersting things: --------------- 4.2. Routing for multiple uplinks/providers --------------- And at the end of the above webpage, it also say the following things: -------------- Note that balancing will not be perfect, as it is route based, and routes are cached. This means that routes to often-used sites will always be over the same provider. Furthermore, if you really want to do this, you probably also want to look at Julian Anastasov's patches at http://www.ssi.bg/~ja/#routes , Julian's route patch page. They will make things nicer to work with. -------------- For my case, I have one ethernet connection to internet, i.e. eth0, and I have serveral vpn connections connected to differert vpn servers of the free vpngate's vpn servers simultaneously. Of course, all of these vpn connections are connected through the physical interface, eth0. In this case, if I want to do multipath routing among these vpn connections for load-balancing, it's possiable for me to use the patches given by Julian Anastasov firstly and then setting the multipath routing based on the instructions of this website: http://lartc.org/howto/lartc.rpdb.multiple-links.html?
