VPN load balancing

[network_a]

Can anyone help me with VPN load balancing? Is it possible with PIX firewall and if yes then how to do?

Is this possible if i am having two different ISP for internet links? Also provide me the links of document if any.

VPN load-balancing on PIX is not supported.

You will need a 3000 series VPN concentrator.

will it be possible with routers

Neither routers load-balance VPN tunnels. Just the Concentrators. You can use routers to load-balance unencrypted traffic but not the VPN tunnels themselves.
