Hi!
I have recently bought a second DSR-500, this time a DSR-500N to set up in my summer house. Now I want to establish a VPN via IP Sec. I have followed the guides that are online but they don´t establish the connection.
Can someone that can understand a logfile please inform me what the probelm is? Log file:
