Provide IP filter services
mount -Ttcpip lsm-ipfilter.so
None.
The lsm-ipfilter.so shared object is the manager that handles IP filtering and NAT (Network Address Translation) services. It is a npm-tcpip.so loadable module. This manager must be loaded to enable filtering and NAT functionality.
IP filtering allows your host to act as a firewall, or you can provide firewall services on your host. NAT allows multiple hosts on a subnet to share a common IP address. Configuration files are used to set filtering and NAT rules. For more details, see /etc/ipf.conf and /etc/ipnat.conf.
