Can't open certain ports

[jinky32]

Hi,

I'm hoping someone can help me out with this - I've spent loads of time trying to sort and it's driving me mad!

So, I am trying to open port 9091 for Transmission but am having no joy. Transmission is installed on my QNAP NAS. I have a number of other ports open for applications running on my NAS (e.g. 9000 for Twonky, 22 for ssh etc) and have forwarded these in the normal way on the 7800 (via virtual server). I can go to https://www.grc.com/x/portprobe=9000 for example and see that these ports are open.

However when I try and forward port 9091 in the same way it just won't work. If I use virtual server to forward then grc.com report the port closed. If i remove the rule in virtual server and just configure the firewall it reports port in stealth. Either way I can never get to fixedinternalip:9091/transmission/web/

I have spent quite a while reading about Transmission config too but I figure if services are reporting the port as closed I need to fix that problem first?

Any ideas of new avenues to explore gratefully received!

Have you tried to DMZ your QNAP NAS for a quick test to see if the DMZ rule allows access to your QNAP NAS device??

Hi,

thanks for your reply. I'm back home now so have tried this out (attached a screenshot in case I did it wrong!). This hasn't made any difference though - grc.com still reports the port as closed. Should adding to DMZ open all ports?

I Just tested a HTTP server set on port 9091 and seems to forward fine.

I added the rule within the virtual server section, then came in on port 9091 via a remote connection and everything worked as it should.
