I ordered a 2nd ip address for my server and put them in the first order in my network configuration.
I do wonder, why this adapted torrcconfiguration:
$> cat /etc/tor/torrc # torrc at tor-relay # PIDFile /var/run/tor/tor.pid DataDirectory /var/lib/tor/data
Nickname zwiebeltoralf OutboundBindAddress 5.9.158.75 DirPort 80 ORPort 443 DirPort [2a01:4f8:190:514a::2]:80 NoAdvertise ORPort [2a01:4f8:190:514a::2]:443
ControlPort 9051
Log warn file /tmp/warn.log #Log notice file /tmp/notice.log #Log info file /tmp/info.log
ExitRelay 0 IPv6Exit 0
works at the first glance (about 6,000 connection) but still give after a while in the log:
Feb 06 19:59:08.000 [notice] Tor 0.4.0.1-alpha opening log file. Feb 06 20:19:26.000 [warn] Your server (<xx>:80) has not managed to confirm that its DirPort is reachable. Relays do not publish descriptors until their ORPort and DirPort are reachable. Please check your firewalls, ports, address, /etc/hosts file, etc.
(where <xx> is the new main ip address at my eth0 device)
