New to VPN, I would like to establish a VPN from a remote site using a 2516
which can be replaced with a 2620. The remote site connects to central using T1, when the T1 fails I would like to establish a ISDN VPN to the central site. The central has a 2620 setup as the border router, pix515 and ids. This is a private network, no isp for internet access. We want to establish a VPN between site using the IE browser. Is there sample configuration I can read to create this scenario.
