Prior to purchasing a SURF SOHO router I had my own OpenVPN server. Because the SURF SOHO implements remote access via OpenVPN I turned off my server and started using the service in the SURF SOHO. I have two questions:
1) How can I find out information about login attempts? With my old server I would
see constant attempts to access the VPN service logged in my system logs and
I could block repeated attempts (none of them ever succeeded because I used
client certificates not passwords). I assume that there are probably constant
attempts to access the port still.
- How can I block access to the VPN service? Passwords are insufficient because
the password size limit is way too small to prevent sophisticated brute
force hacking attempts (and the router doesn’t support using OpenVPN client
certificates). I want to be able to firewall IP ranges but none of the firewalls
seem to be applicable (I thought the service firewall was the one to use but it
only lists the Pepwave VPNs not the OpenVPN service).
Thank you.
