nat redirect_address 192.168.1.2 192.1.1.1
nat redirect_address 192.168.1.3 192.1.1.2
In this case all traffic incoming to 192.1.1.1 will be redirected to the LAN address
192.168.1.2, and traffic incoming to 192.1.1.2 will be redirected to 192.168.1.3.
Address redirection makes sense when there are several IP-addresses on the same
host. In this case NAT can assign to every LAN client its own external IP-address.
Then NAT transforms outgoing packets, changing IP-addresses to public external
IP-addresses. For example, IP-addresses 128.1.1.1, 128.1.1.2, 128.1.1.3 belong to
the gateway. 128.1.1.1 can be used as public gateway IP-address, and 128.1.1.2
and 128.1.1.3 will be redirected to LAN clients A and B:
nat redirect_address 192.168.1.2 128.1.1.2
nat redirect_address 192.168.1.3 128.1.1.3
redirect_proto proto local_addr [public_addr [remote_addr]]
Redirects all the incoming packets with specified protocol proto to the host with
address local_addr.
nat default_h323 [yes|no]
Includes address modification according to H.323 stack for outgoing connections.
Affects all incoming UDP packetsd destined for port 1719 and incoming TCP
connections for port 1720. By default disabled.
nat h323_destination ras|cs remote_addr[:remote_port]
[local_addr[:local_port]]
Enables to describe more specifically using of H.323 elements in the external
network.
 ras|cs - H.323 stack layer specified for processing.
 remote_addr - address of external network, its connections will be processed.
 remote_port - port, its outgoing connections will be processed. If port not
specified then used value 1719 for ras and value 1720 for cs.
CAUTION
Do not enable this option unless needed, because this will hinder NAT performance if not used in IP
telephony applications.
