Hi.

I have 2 T1 from 2 different ISP which require me to use their own Cisco routers for the 100% uptime guarantee.

Can I get a VPN gateway with dual WAN ports with outbound load balancing so I can both T1 connections without changing the Routers from the 2 different ISP?

Can these devices function between my router and network(or does it have to act as my router?)

Such as :

or

Do I have to have both T1 circuits from the same ISP which terminate on the same router or can I use a dual WAN VPN gateway to do this after my routers?


Sorry if this is a newbie questions.

Thanks.
