Re: Filtering traffic from your node - for exit points

Torified User,

It's possible to block certain IP addresses and ports in the torrc.
Please continue to run an exit server that blocks certain IPs and ports,
that will improve the network as Tor will only rout allowed traffic
through your node.
But blocking by content without the possibility to configure it in the
torrc file will make the Tor network slower and will make some downloads
and browsing fail from your exit server. If Tor in the future allows
content filters, then it will be possible to run a filtered exit server
without slowing down the network.
I hope Tor will allow content filer in the future as it would make more
people run exit servers. Of course I hope there will always be exit
nodes running without any blocking at all, as content blocking often
block good things too.

It must be the Tor users choice and not the exit server admins choice
what the users will do or not do. And it must be the criminal users the
are taken by the police, not the exit server admins. And it must be the
exit server admin's choice wheter or not he/she will take the risk of
getting his equipment confiscated by the police. Combining these
important things is difficult, but as long as exit servers with
different configurations exist in many countries with different laws it
will be possible to have access to the full internet from any country
through the Tor network.

I myself live in the EU and I don't dare to run an exit server because
the torrc would get really huge if I added all the IPs I would like to
block to be sure to not get my computer confiscated by the police. And
still I wouldn't be secure as new child porn sites, and terrorist sites
appear all the time.

My main reason to run a server is to be an entry server on a common SSL
port in order for people behind restrictive firewalls to get access to
the internet. But I would probably run an exit server if I was sure not
to get a policeman knocking on my door one day.
