Can someone tell me why the firewall log shows port 10001 being dropped when I have it listed in the port forwarding table in my Netgear WNR3500v2?

Thanks

I ran across a bug just the other day where leaving the Application field blank corrupted the port forward. However, it was obvious that it was corrupted based on what I saw in the fields after hitting Save; everything was shifted down one field to the right. So I wouldn't be surprised if perhaps you're having a similar problem (minus the visual cues).

If it still doesn't work, then dump the nat table (where the port forwards are handled) and let's see what the GUI generated. Perhaps that will reveal the problem.

Code:
iptables -t nat -vnL

@Aux Memes

It's probably best and polite to resize your image first as requested by the Guru's, and then you'll probably get a response. I use the following program for a Windows setup...


https://filehippo.com/download_image_resizer_for_windows/


As suggested, use the following dimensions - 800 x 600 / 960 x 720

Google for Mac alternatives...

All the best...

??? Or use the resize option in the default Microsoft Photos app that is pre installed...

Either way....you are being ignorant by not bothering to follow simple rules...or requests Rolling Eyes

LOL, I see white space for the most part, now it is utter useless Sad

So just to take a stab at it: in source always use 0.0.0.0/0

Yes, all kinds of whitespace. The overall image size is still huge. And, yeah what egc said on the solution is as best I can guess.... Rolling Eyes
