I have been trying to establish a vpn between two sites but cannot get it established to save my life. I am rather new to vpn's and deeper networking in general. I am trying to establish it between site b(my site) and site A. Site A and Site C have a vpn in place, which has been established by a previous company. I do not have much experience with cli commands but can pick up pretty quickly. Currently, i am using asdm. Both Site B and Site A have ASA 5510.
Is it more complicated since there is already an established vpn? When i try to trace the route, it seems to be looping in my isp's routers.
