Remember that you can only load balance outgoing IP traffic. Even traffic shaping can only be done on outgoing traffic. If you want full link aggregation you should keep the same setup on the ISP side also. I dunno about Linux. With OpenBSD you can do this with trunk(4) interfaces. You can also use equal cost multipath routing. Or you can use BGP if there are BGP speakers. The final way is by using pf(4) to do route-to() between the two outgoing interfaces. In other words there are 4 ways to achieve this. With OpenBSD which is truly open source unlike Linux. -Girish _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
