Hello Markus,
it's correct that Freenode is blocken every Tor exit node because they don't want you to connect over the internet.
Please use the hidden service from Freenode.
There should be a howto on the website of Freenode.

Hello Markus,

I know that maybe it's too late to answer, and I don't even know
if the answer is right but, Freenode has some hidden servers
don't you know? Take a look at https://freenode.net/irc_servers.shtml,
there are 4 addresses to connect to freenode through Tor Onion
network. I don't know if I'm right, but I actually want to use freenode
even with a tor relay running on my router, let's try to do that helping each
other...

Sorry about my poor english...

Best regards,
UserX
