Hi - I just picked up my new Hitron modem this afternoon and noticed a strange entry in the port forwarding section. Is the Teredo application critical to the Hirton's function? What is the purpose of the Teredo application? Thank you
Teredo tunneling - Wikipedia
Teredo is a Microsoft created IPv6 over IPv4 tunneling protocol. This looks like a UPnP created port forwarding rule that some device on your network added. It could legitimately be Teredo, or it could be some other application opening itself a hole to the outside world.
You'll have to investigate your local network and devices to find out which machine as IP address 192.168.0.14 on the local LAN, and what application on this machine opened those ports via UPnP.
TL;DR: You're either A-OK, or have Malware on the computer with IP address 192.168.0.14
