Chapter 4 - Layer 3 Command Set - IP Networking Nat Command (Network Address Translation)
Alvarion BreezeNET B130/B300 GigE 201 Operational User Manual
If you are using several pairs of public address-private network, it is
recommended to specify the exact public address.
Parameters remote_addr and remote_port_range may be specified for more
exact definition of incoming packets (packets only from specified source and port
will be allowed). If remote_port_range is not specified then its range should
coincide with range of public_port_range.
nat redirect_port tcp 192.168.1.5:23 7777
In this example all incoming tcp connections to port 7777 will be redirected to
host 192.168.1.5 port 23 (telnet).
nat redirect_port tcp 192.168.1.4:2300-2399
123.1.1.2:3300-3399
All incoming tcp packets with public_port range 3300-3399 and destination
address 123.1.1.2 will be redirected to 192.168.1.4. Port mapping is "1 to 1", i.e.
3300->2300, 3301->2301.
For example, IRC-server is running on client A and WEB-server is running on
client B. Then in order to get it work, connections accepting on ports 6667(irc) and
80(web), should be redirected to the appropriate hosts:
nat redirect_port tcp 192.168.0.2:6667 6667
nat redirect_port tcp 192.168.0.3:80 80
Second type:
redirect_port proto local_addr_1:local_port_range[,
local_addr_2:local_port_range, …]
[public_addr:]public_port_range
[remote_addr[:remote_port_range]]
Cyclic redirection of incoming packets to several destination addresses for
uniform load distribution between them (LSNAT):
nat redirect_port tcp 192.168.1.2:80, 192.168.1.3:80
123.1.1.2:80
In this case all requests to WEB-server 123.1.1.2 will be redirected to the LAN
servers.
nat redirect_address local_addr [,local_addr,…] public_addr
Redirects all incoming traffic directed to public_addr to local_addr. If several
local_addr addresses specified then redirection will be done in round-robbin
fashion.
