I have a Cisco 819G router which I've setup to use ADSL on the Dialer0/Gigabit0 interface, and 3G on the Dialer2/Cellular0 interface. The only other site is the data centre (DC), which is running off a single ASA with a public IP. There is a single server in the DC with the IP 172.16.1.1. I want to make connections to the DC through a VPN to the ASA running off both the ADSL/Dialer0/Gigabit0 interface and the 3G/Dialer2/Cellular0 interface. So I want two VPNs active to the DC load balancing between the two.
The current running configuration is below. I can run any commands on this service you like. The ADSL service is currently unplugged as it's supporting the client's existing setup while we get this Cisco router right, but I can arrange to have it connected after hours to test it.
QUESTION: Is there a way to have two VPN tunnels between the same source and destination at the same time, but running over different connections?
QUESTION: Is there a way to load balance between these two VPN tunnels and failover to the other tunnel should the 3G or ADSL service fail?
QUESTION: Occasionally this VPN tunnel will close and won't re-establish unless I issue the below commands to clear and reinitiate the VPN. Is there a command or a script I can run to fix this issue?
