I'm configuring Firewall in the server running Conectiva Linux 6.0 (Brazil) and I already configured to accept connections in the ports: netbios-ns 137/tcp # NETBIOS Name Service netbios-ns 137/udp netbios-dgm 138/tcp # NETBIOS Datagram Service netbios-dgm 138/udp netbios-ssn 139/tcp # NETBIOS session service netbios-ssn 139/udp I'm using the IPCHAINS and I configured in this way: ipchains -A input -i $EXTERNAL_INTERFACE \ -s $ANYWHERE $NETBIOSPORTS -p tcp \ -d $IPADDR $NETBIOSPORTS -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE \ -s $IPADDR $NETBIOSPORTS -p tcp \ -d $ANYWHERE $NETBIOSPORTS -j ACCEPT ipchains -A input -i $EXTERNAL_INTERFACE \ -s $ANYWHERE $NETBIOSPORTS -p udp \ -d $IPADDR $NETBIOSPORTS -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE \ -s $IPADDR $NETBIOSPORTS -p udp \ -d $ANYWHERE $NETBIOSPORTS -j ACCEPT Please, if someone knows what is happen, please, anwser me...
