Port Forwarding set-up on T3200M / Firewall set-up
Hi there! I have recently logged-in into the settings of my T3200M modem from Telus to check how the firewall was set-up, and I discovered that there were lots of port forwarding rules set-up on ...
You should read up on UPnP. That is where all of those entries will have originated from and not from Telus. UPnP allows devices, and even software like games, to set up entries in the routing table so that they can receive data on a specific port and device on your home network. If you were to delete the entries and still had UPnP enabled, they'll just appear again once you use the device (PC, console, etc) or the software that originally created the entries in the first place. If UPnP was disabled, and it's not hard to do, then if you try to use a device or software that needs certain entries to work, you'd have to do that manually, assuming the device or software has the instructions available on what ports to use. Some sites do recommend disabling UPnP.
The firewall being set to NAT only isn't bad especially if you do any gaming.

Community Power User1. I checked port forwarding on my T3200 and aside from the rules I've created the only ones there are for the Telus Wi-Fi access point.
2. What do you consider adequate? Unless you have specific requirements I would stick with the default.
Thank you. Looks like this was done my my NAS via UPnP. By “adequate” I mean “safe enough” or “most recommended” for an average user. E.g. UPnP seems to be enabled by default on most routers - yet, from what I read, most sources recommend turning it off.
