A
Network Address Translation Router
-
Fusion™
NAT
Part of the Fusion Suite of Embedded Networking
Protocols from Unicoi Systems, Inc.
Fusion Embedded NAT Router
software allows client IP hosts on a private network
to access Internet hosts without having to obtain
public IP addresses. It works by modifying the IP
layer header’s source address and selected
fields in upper layer protocol so that the private
internal IP address is replaced with a "Real"
assigned IP address which can safely traverse the
Internet. Once the NAT router is assigned at least
one "Real" IP address, up to sixty-four
thousand IP client machines can share this address
simultaneously to access Internet hosts.
Fusion
NAT Router features:
- Integrates
seamlessly with: TCP, UDP Routing, ICMP, PING,
Telnet, FTP, HTTP, DNS and other Internet Protocols
- Connection
aging, TCP open and TCP closed, UDP and ICMP.
Limit on the number of simultaneous connections
supported can be set as high as memory will
allow (defaults to 20).
- Outbound
FTP (PORT Command Translation)
- PAT
(Port Address Translation) allows specific services
on the private network to be accessed by host
on the public network
- Gated
NAT - Each router port gets its own instance
of NAT. Each port can have its own public address
and private address range. This means that NAT
can be supported on more than one link without
regard to the address ranges in use. The public
address can be the dynamic address from a numbered
PPP link, if required.
- Conventional
NAT - Can be implemented by creating one global
NAT port and calling the NATTranslate function
in the FUSION IP ip_up and ip_xmit functions.
- NAT
Profile - may be used by more than one port
- 100%
ANSI C compliant
- RTOS
and processor independent
