Devices ASA 5510, remote router Linksys RVS4000, Client OS Vista Ultimate 64bit. Problem: After signing in to Cisco Easy VPN, authentication succeeds and checks for updates, begins to set up connection to VPN server, midway through an error pops up "Could not verify IP fowarding table modifications, VPN connection couldn't be established" What could be the cause?? There are about 2-3 other users with different routers and OS that are having the same issue.
