Thanks screenie for your reply. I'm a newbie in Juniper routers

. I tried to do unequal load balancing on SSG, but unsuccessfully. I have two site-to-site VPNs with different bandwidth between two sites and I try to use them fully.
Do J2300 have true per-packet load blancing or actually it is per-flow load balancing? Also is it possible to do percentage load balancing on j2300 (for example 30% of traffic direct to VPN1 and 70% to VPN2)? I read that it is possible with MPLS, and what about OSPF, BGP and static routing?
Thank you in anvance!!!
