Curious about "ip link" interface output - "tunl0" ?
Hello. Have a ReadyNAS RN102 that i am enjoying quite nicely as using for a remote offsite backup/streaming storage pool. But, I have enabled SSH access, and once logged in i was surprised at the results of "ip link" :
What is the "tunl0" interface's purpose/use?

- That is used by our software VPN for providing you secure remote access to your NAS.
Welcome to the forum! - Thanks for the welcome!
Would this "software VPN" happen to be OpenVPN, by any chance?
