I use slackware 10.2
and have oidentd 2.0.7 installed
and I use a NAT router for my connection
oidentd worked fine until i switched DMZ in the router to my box
then it sudenly stoped working, port 113 is forwarded but no ipv4 irc server connects to it
meanwhile ipv6 irc server connects to it with no problem

Oct 16 15:13:41 rootservers oidentd[27208]: Connection from eu.irc6.net (2001:ad0::6667):53554
Oct 16 15:13:41 rootservers oidentd[27208]: [eu.irc6.net] Successful lookup: 42267 , 6667 : deevee (deevee)


and this is the output of nmap localhost:
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
37/tcp open time
53/tcp open domain
80/tcp open http
111/tcp open rpcbind
113/tcp open auth
548/tcp open afpovertcp
587/tcp open submission
631/tcp open ipp
953/tcp open rndc


anyone has any idea what's wrong?
