NOTE The UC-8410/8416/8418 does NOT support IPV6 and ipchains.
The basic syntax to enable and load an IPTABLES module is as follows:
#lsmod
#modprobe ip_tables
#modprobe iptable_filter
Use lsmod to check if the ip_tables module has already been loaded in the UC-8410/8416/8418.
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
NOTE IPTABLES plays the role of packet filtering or NAT. Take care when setting up the IPTABLES
rules. If the rules are not correct, remote hosts that connect via a LAN or PPP may be denied
access. We recommend using the serial console to set up the IPTABLES.
