SecureNAT is off, still seeing unknown hosts on interfaces
Posted: Thu May 11, 2017 3:59 pm
Hello,
I can see SoftEther VPN Server and VPN Client (both Debian) getting weird traffic on their respective virtual TAP interfaces.
It's all ARP traffic as far as I could see (unknown host asks my primary TAP address for who-has and gets a reply).
I read that this could be due to SecureNAT feature enabled for Virtual Hubs. I disabled it, but I still can see these garbage ARPs.
Since I plan to route quite a number of networks via this main VPN Server, I need to be 100% sure there's no virtual hosts taking address space.
Advice please?
Thank you.
