[tor-relays] Unreachable ORPort - Potential ISP block?

[Julien ROBIN]

Hi,


One thing you have to be sure :

  - Is you external IP address directly assigned to your Router ? The IP address given by www.whatismyip.com shoud be readable somewhere on your router. If not (like for mobile data Internet access : a kind of "local" IP address is given to your router device, and it doesn't matches with your external IP address), your router's IP address simply cannot be contacted from the outside :( so it has nothing it could receive and forward, even if well configured. I hope it's not the case for you ! It's the case with my mobile data provider, but I never saw this with a wired line provider.


If nothing wrong and your router is connected using your external IP address, a good way to be sure is to try other services (like apache2, on port "80" or another). Things that should work !

As said Robert, if nothing works, check "firewall" rules into your router. Inside your raspbian too, but I don't remember having anything inside Raspbian telling me "no" when a process or service successfully opened a listening socket (apart from a non root process trying to listen on a < 1024 port)

Also, do not hesitate to try with other computers, with a Filezilla Server on Windows for example, in order to be sure that nothing escaped from your vigilance (a kind of double check so different that you cannot repeat 2 times the same error, if there is one)


If everything but Tor is reachable, and "netstat -n -l -p" is showing your Tor process listening on globally (0.0.0.0), may be your ISP is involved in this problem ! But it would be a bit strange, and so disappointing.


Good luck !

Object: [tor-relays] Unreachable ORPort - Potential ISP block?



I'm attempting to run a Relay but I haven't been able to get it the ORPort to be confirm as reachable. I've tried lots of things but I'm hoping there is something I haven't thought of yet that can make this work! I've got a 50Mbps symmetrical connection (without data caps) that I would love to have the Tor network utilize. 


Hardware info: 
- Asus RT-N66U running DD-WRT 
- Raspberry Pi 2 running Raspbian 
- SanDisk MicroSDHC UHS-I 16GB 


Here are all the steps I've taken: 

- Formatted the MicroSDHC with Win32DiskImager. 
- Followed the Instructables Raspberry Pi Tor Relay configuration guide. 
- Port forwarded via NAT/QoS then Port Forwarding. Protocol is set to TCP, double-checked IP is what is assigned to Raspberry Pi 2 and enable box is checked. 
- ORPort set to 9001. Also changed ORPort to 443, did "sudo service tor reload" and changed the port in the forwarding section of my router. 
- Tried router DMZ for Raspberry Pi LAN IP. 


I would really like to get this to work, if possible. I can't run an Exit node on my connection but since my connection sits unused for most of the day it should be put to good relay use.
