A ClearOS (or whatever other Linux&#x2F;BSD gateway&#x2F;firewall distro you like) add-on&#x2F;plugin that blocks access to&#x2F;from Tor. Basically a thing that takes the torproject&#x27;s published exit node IP address list that updates every 30 minutes &amp; plugs those addresses into IPTables- or something along those lines. Currently this functionality doesn&#x27;t exist for firewall&#x2F;gateway distros (AFAIK).
