I'm looking for a valid configuration of an IPv6-enabled Tor Bridge. I have working IPv6-enabled relays, now I'd like to have a bridge (and not to loose IPv4 clients). I wonder if adding the following configuration will be enough:

BridgeRelay 1
ServerTransportPlugin obfs3,scramblesuit exec /usr/bin/obfsproxy managed
ServerTransportListenAddr scramblesuit [::]:52176
ServerTransportListenAddr obfs3 [::]:40872

I have verified that I connect to these ports using IPv4, but I am not sure if the Tor infrastructure will be able to cope with this configuration.

There are no IPv6-specific stuff in torrc, but make sure to check all theese points :

  • You're running a system with IPv6 functionality enabled
  • You have compiled all the pre-requisites of Tor and the Tor itself without IPv6-disabling flags
  • You better run a local instance of ISC Bind with IPv6 and IPv4 enabled, to make sure your DNS resolving won't be glitchy.
