EDIT: My VPN has port forwarded a 5-digit tcp/udp port for me.
What kind of attacks am I opening the computer to with VPN port forwarding?

1 Answer 1


Any open port is susceptible to probes/attacks, it all depends on what service/application is running on it and how vulnerable is that service/application itself.

For VPN:

  • If using application, you need to find out how vulnerable is your VPN application.
  • What cipher suits are used.
  • Implement strong authentication measures.
  • Keep log of connections.
  • AES-256, SHA1, RSA-2048, udp-connection, no dns leaks
