Please explaing about VPN load balancing based on a scenario where two ISPs are there. How can i configure vpn load balancing in such a scenario ?
what type of VPN connections do you want to load balance ? Remote access vpns right ? you can basically configure a cluster within your VPN device to load balance traffic locally, which comes through the same ISP .. but for a scenario with 2 different ISP's , it might look a bit tough.. Just because of the fact that your vpn device will have two different IPs on the external side, and have to terminate on two different interfaces... tracking and clustering two interfaces is tough ... moreover your VPN clients will point to a single IP address from either of the ISPs, and having virtual IPs in this case is difficult...
Hope this helps... all the best..
