I got a new monoprice router, but it oddly didn't come with any port forwarding, only triggering. I've only ever  forwarded and thought it would have the same result.

 

Here's a screenshot of the configuration I though was going to work.    http://i.imgur.com/GGp4AoZ.png

 

I never need to forward ports for anything anymore, so... If I have to, I'll just put the raspberry pi in the dmz.

 

Any help would be appreciated ^-^

Port triggering is the same as forwarding except you don't have to set a static IP address on your host, so to answer your question.... Yes, same result with less hassle.

I don't know what I'd be doing wrong then :\ . I have it set as you see in the screenshot. However, I can't access my mumble server or even ssh into it. The minute it put it into the dmz, i can access it.

 

Do you see any issue with how I have it set?

Here's the difference pointers out of my networking rule book

 

  • Port triggering can be used by any computer on your network, although only one computer can use it at a time.
  • Port forwarding is configured for a single computer on your network.
  • Port triggering does not need to know the computer's IP address in advance. The IP address is captured automatically.
  • Port forwarding requires that you specify the computer's IP address during configuration, and the IP address must never change.
  • Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity.
  • Port forwarding is always active and does not need to be triggered.

 

What other options are you seeing in the dropdown for the protocols? Is SSH in there? Is there an "All" option?

That's all as I suspected. However, I'm just lost at this point. From my perspective I see nothing being done incorrectly to just let the mumble server run.

 

Oh well, I'll just keep it in the dmz and report back if I really ever need to get it working for something else :P

Okay, for sure... I only know the theory, as I only use port forwarding, but I can't see an issue with your setup either. (unless of course the router isn't getting the trigger it is expecting? maybe it is a more product specific setting that requires research?).

 

Good luck :busy:

SSH is strictly TCP so remove that UDP. It's pointless to trigger port 22. If you connect outbound to a server then it opens. If you setup a SSH Server inbound traffic is going to hit a brick wall as the port 22 is not forwarded it's triggered. If you setup a SSH Server then it would be wise to generate 2048bit keypair, no password, no root login and change it's port to something more obscure like 2222 in the servers conf file. Just saying.
