Moxa UC-8410A-T-LX [50/86] Modprobe iptable_filter

UC-8410A Series Linux Software General Debian Package Usage

5-10

The UC-8410A-LX supports the following sub-modules. Be sure to use the module that matches your

application.

The most common modules are already built in to the kernel:

ip6t_eui64.ko ip6t_ipv6header.ko nf_conntrack_ipv6.ko xfrm4_mode_tunnel.ko

ip6t_rt.ko ip6t_LOG.ko xfrm6_mode_beet.ko ah4.ko

ip6table_security.ko ip6t_ah.ko sit.ko xfrm4_mode_beet.ko

ip6table_filter.ko ip6_tables.ko ipv6.ko xfrm4_mode_transport.ko

ip6t_frag.ko ip6table_raw.ko xfrm6_mode_tunnel.ko esp4.ko

ip6t_hbh.ko nf_defrag_ipv6.ko xfrm6_mode_transport.ko ipcomp.ko

ip6t_REJECT.ko ip6t_mh.ko xfrm_ipcomp.ko tcp_diag.ko

inet_lro.ko xfrm4_tunnel.ko inet_diag.ko

The basic syntax to enable and load an IPTABLES module is as follows:

Use

lsmod to check if the ip_tables module has already been loaded in the UC-8410A-LX series. Use

modprobe to insert and enable the module.

Use the following command to load the modules (iptable_filter, iptable_mangle, iptable_nat):

#modprobe iptable_filter

Use iptables, iptables-restore, and iptables-save commands to maintain the database.

NOTE

IPTABLES plays the role of packet filtering or NAT. Take care when setting up the IPTABLES rules. If the rules

are not correct, r

emote hosts that connect via a LAN or PPP might

be denied access. We recommend using the

serial console to set up the IPTABLES.

Since the IPTABLES command is very complex, to illustrate the IPTABLES syntax we have divided our

discussion of the various rules into three categories: Observe and erase chain rules, Define policy rules,

and Append or delete rules.
