lsm-ipfilter-v4.so, lsm-ipfilter-v6.so

Provide IP filter services

---

These modules are available only in the Extended Networking Technology Development Kit (TDK). The TCP/IP stack looks for the correct version of this module when you mount it (i.e. lsm-ipfilter-v4.so with npm-tcpip-v4.so; lsm-ipfilter-v6.so with npm-tcpip-v6.so).

---

Syntax:

mount -Ttcpip lsm-ipfilter.so

Options:

None.

Description:

The lsm-ipfilter-v4.so and lsm-ipfilter-v6.so shared objects are the managers that handles IP filtering and NAT (Network Address Translation) services. The npm-tcpip.so shared object can load these modules. You need to load this manager 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.
