Re: [tor-relays] ORPort NoAdvertise & NoListen Not Working

All:

It turns out that this issue was related to PortForwarding to the Private Gateway Address (192.168.0.1:9001).

The solution was to include an iptables ACCEPT Rule in the INPUT Chain to the PortForward destination (the Private Gateway Address - 192.168.0.1:9001).

# iptables -I INPUT -p tcp --dport 9001 -j ACCEPT

# iptables -A VSERVER -p tcp -m tcp --dport 443 -j DNAT --to-destination 192.168.0.1:9001

Now, the Tor Self-Test is returning successfully. However, now, there is an issue with the written/read bytes per second graph, on the metrics.torproject.org site, dropping to zero.

Any idea why PortForwarding would cause the written/read bytes per second graph to drop to zero?

Respectfully,

Gary

All:

After reviewing several packet-traces of Tor bound directly to the Public Address:Port vs Tor bound to the Private Address:Port and Advertising the Public Address:Port, I believe I may have found the the issue.

It appears that when Tor is bound directly to the Public Address:Port, the initial measurement connections are initiated from External Tor Nodes via High-Ports to the Public Address:Port over TLSv1.2 or TLSv1.3 successfully passing self-test. However, when Tor is bound to the Private Address:Port and Advertising the Public Address:Port, the initial measurement connections are initiated from External Tor Nodes via High-Ports to the Public Address:Port over TLSv1.0. Tor does not like the TLSv1.0 connections and Resets the them; thus, failing the self-test.

The question is... Why are the initial measurement connections initiated from External Tor Nodes via High-Ports with the Private Address:Port binding and Public Advertised Address:Port combination over TLSv1.0?

Has anyone successfully implemented the Private Address:Port binding and Public Advertised Address:Port combination that successfully passes self-test whom would be kind enough to share their configuration?

Is there a way to force the External Tor Nodes that initiate the measurement connections to use TLSv1.2 or TLSv1.3 with the Private Address:Port binding and Public Advertised Address:Port combination?

Thanks, again, for your assistance.

Respectfully,

Gary

David,

The ISP has port 9001 blocked to the Public Address.

Do the ports have to be the same, when using NoAdvertise & NoListen with the ORPort directive?

Thanks!

Why two different ports?
