The ‘Dynamic' mark may be missing. And in the ip-Address there is no address for the vpn. So the connection couldn't be established.
The vpn connection could still work on another router in the same network. Reboot the routerboard doesn't work at all.
I have experienced this three times or more. All I can do is to reset the routerboard and reconfigured the router. But it's too troublesome.
How can I solve this?
