I found the culprit, for my eyes its a problem with ipfw.
Look here:
on titan the rule 100 doesn't work anymore for (for me) unknown reason:
00100 0 0 allow ip from any to any via lo0
00200 3 180 deny ip from any to 127.0.0.0/8
00300 0 0 deny ip from 127.0.0.0/8 to any
65000 133 75074 allow ip from any to any
65535 21787 2611732 deny ip from any to any

On my Laptop aklemm the rule 100 (firewall type "open") works:
00100 206 20504 allow ip from any to any via lo0
00200 0 0 deny ip from any to 127.0.0.0/8
00300 0 0 deny ip from 127.0.0.0/8 to any

Because rule 100 isn't working for unknown reason on titan,
I get DNS and connect problem with a local NNTP server, since the
traffic pattern "from any to any via lo0" is needed, but doesn't work.
But I really have no idea, whats that causing...
