interface { name } { index } nat-group { list-id }
Important
Each network interface supports only one NAT list.
4.8.2.1. Examples
Example 4.73. Simple NAT
If a private network 192.168.1.0/24 is connected to FastEthernet 0 , and WAN interface Wireless
0 has an external address 10.0.0.1 , then simple many-to-one SNAT can be enabled like this:
nat-list 110 snat 192.168.1.0 0.0.0.255 any to 10.0.0.1
interface Wireless 0 nat-group 110
Example 4.74. Masquerade
In case the external interface address is unknown (e.g. dynamic):
nat-list 120 masquerade 192.168.1.0 0.0.0.255 any
interface Wireless 0 nat-group 120
Example 4.75. Port forwarding
If the private network has an internal web server 192.168.1.10 and it's needed to give access to
it:
nat-list 120 dnat any any eq 80 to 192.168.1.10 eq 80
nat-list 120 dnat any any eq 443 to 192.168.1.10 eq 443
nat-list 120 dnat any any eq 8080 to 192.168.1.10 eq 8080
interface Wireless 0 nat-group 120
4.8.2.2. Viewing NAT lists
The
show nat-list [89]
command displays the contents of NAT rule lists:
show nat-list

4.9. PPP
4.9.1. Overview
LibraPlus supports up to 10 concurrent PPP client connections. Each connection can be configured
using the
interface command section followed by the PPP interface type and an interface index. PPP
in LibraPlus is used as a transport for the IP protocol and supports PPTP and PPP over Ethernet en-
capsulation.
