I have one doubt actually, suppose i have Three ISP and i want to use all three ISP at a same time in my environment.
how can i do it.
thanks in advance.
Please see this thread: ISP Redundancy with 3 ISPs
If you actually have at least two /24 or larger ranges of public IPs from your ISPs, you can use BGP for limited load balancing on your perimeter routers and have Check Point configured for normal ISP redundancy.
In addition to what Vladimir said checkpoint supports only 2 ISPs for redundancy your best option is to use dynamic routing.
