ufw

On a ubuntu 10.0.4 server runs redmine. starting webrick with:

./server webrick -e production -b lvps46-173-79-113.dedicated.hosteurope.de -d

makes redmine available in browser. as soon as we enable ufw, webrick can´t be accessed anymore. of course we allowed Port 3000 from anywhere

ufw allow 3000/tcp
ufw allow 3000/udp

also a grep for iptables doesn´t show a deny rule

iptables -nL | grep 3000

find the whole iptables output here http://pastebin.com/k6WNqdPU

checking

lsof -ni tcp:2222

tells me ruby is listening on port 3000

ruby    3457 root    5u  IPv4 864846667      0t0  TCP 46.173.79.113:3000 (LISTEN)

What else can we check? what´s wrong with the ufw rules for port 3000?
