+       help
+         NetBIOS name service requests are sent as broadcast messages from an
+         unprivileged port and responded to with unicast messages to the
+         same port. This make them hard to firewall properly because connection
+         tracking doesn't deal with broadcasts. This helper tracks locally
+         originating NetBIOS name service requests and the corresponding
+         responses. It relies on correct IP address configuration, specifically
+         netmask and broadcast address. When properly configured, the output
+         of "ip address show" should look similar to this:
+
+         $ ip -4 address show eth0
+         4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000

+         This module adds support for PPTP (Point to Point Tunnelling
+         Protocol, RFC2637) connection tracking and NAT.
+
+         If you are running PPTP sessions over a stateful firewall or NAT
+         box, you may want to enable this feature.
+
+         Please note that not all PPTP modes of operation are supported yet.
+         Specifically these limitations exist:
+           - Blindy assumes that control connections are always established
+             in PNS->PAC direction. This is a violation of RFC2637.
+           - Only supports a single call within each session

+         SIP is an application-layer control protocol that can establish,

+         Internet telephony calls. With the ip_conntrack_sip and
+         the nf_nat_sip modules you can support the protocol on a connection
