tbb-firewall-ports link from "the firewalled-clients FAQ entry" is out of date
FAQ pages > I'm behind a NAT/Firewall > the firewalled-clients FAQ entry: https://support.torproject.org/tbb/tbb-firewall-ports/
The first suggestion, to visit portforward.com is bad. Portforward simply wants to sell janky software. Their trial version is not helpful; their site does little to help someone with complicated firewall issues.
The second suggestion is out of date: Adding "FascistFirewall 1" or "ReachableOR Addresses/ReachableDir Addresses" to torrc produces error messages and blocks startup.
Error message example:
Nov 08 03:50:33 DietPi tor[4265]: Nov 08 03:50:33.820 [notice] Read configuration file "/etc/tor/torrc". Nov 08 03:50:33 DietPi tor[4265]: Nov 08 03:50:33.823 [warn] The ReachableDirAddresses option is deprecated, and will most likely be removed in a future version of Tor. It has no effect on relays, and has had no effect on clients since 0.2.8. (If you think this is a mistake, please let us know!) Nov 08 03:50:33 DietPi tor[4265]: Nov 08 03:50:33.824 [warn] Failed to parse/validate config: Servers must be able to freely connect to the rest of the Internet, so they must not set Reachable*Addresses or FascistFirewall or FirewallPorts or ClientUseIPv4 0.
The firewalled FAQ web page is pretty useless at this point. Should be updated.
