Hello. I have a problem, these networks don't have Internet access, so I can't ping a valid address like 8.8.8.8, the networks are inside an IPSEC tunnel.
So I ping from one router to the other, but when I change track 10 to 20, it doesn't go back to 10 when the internet is restored.
I use these settings on a Cisco 3750 Switch as the network core.
