hello.. it is possible for cisco asa 5510 to have load balancing between dual isp? and what will be the configurations? thanks... :D
Normally for load-balancing on network devices PBR is used. I'm quoting from another of my posts on this forum:
The ASA/PIX does not support PBR to date. I've been told its on the roadmap.
As a work around, you could run multiple contexts, if its possible to break your lan subnets into two.
And also allocate the appropriate Internet interfaces to each context (with the default gateway pointing to the respective ISPs).
This link will get you started:
PLEASE NOTE: Dynamic Routing and VPNs are not supported in Multiple Context mode.
Another alternate, if the WAN links are terminated on a router (and not the firewall), you could use that router to do the PBR.
