Question:

Non-Nebula VPN montior show connected, but no traffic can't pass through, how to check ?

Answer:

1)Please log in Firewall by SSH and verify the VTI is exist and up

The VTI interface is VTI_{Your VPN name} with vtiX

2)If you have manual VTI address, checking you have correct routing settings

3)For this exampel,trying to capture packets on vti0, You should be able to see the request/reply traffic via vti0

Router> packet-trace interface vti0
