Forwarded to the list, because of course, I simply cannot work a mailer.... (twice inside a month). - - - - - - Diego, : I have a redhat 7.1 linux box as a gateway firewall with an adsl (ppp0) : with dynamic IP (no static) and I just have add a new ISP with STATIC : IP. Can I do iproute 2 multipath load balancing across both ISP? Yes. : where can I read something about?? Read about multipath routing here: http://lartc.org/lartc.html#AEN287 But in order to understand it you'll need to read about split access routing: http://lartc.org/lartc.html#LARTC.RPDB.MULTIPLE-LINKS : I don't know how can I do with the dymanic IP of my adsl link. Where : can I fount examples of config? Some examples (probably not directly relevant to your needs) are available on the lartc.org site. I presume you're using rp-pppoe for your aDSL link. I'd suggest writing a script to reset the multipath route upon successful ppp0 connection establishment. You should be able to use ip-up.local (or something similar). -Martin -- Martin A.
