Ok,

so thank's for all your answers ... it's working now ...

... but today something strange is happend ...

the host tried to make a connection to an unknown IP on port 137 ( UDP )
... why that ?
... usually Port 137 ( UDP ) is :

netbios-ns 137/tcp # NETBIOS Name Service
netbios-ns 137/udp # NETBIOS Name Service

... here the log-entry :

Nov 28 12:26:22 linux-box kernel: OPEN: 192.168.10.60 -> 213.6.48.154 UDP,
port:137 -> 137

... anybody an idea ??? should I deny any connections from host to internet
on this port ???

Mit freundlichen Grüßen
Bruno Leonhardt
