ExtremXOS IP Network Address Translation (NAT)

Network Tackle Translated (NAT) maps INDUSTRIAL addresses from one site domain (typically secret IP address spaces) to an another address domain (typically public Internet IP address spaces) to offers transparent routing to end hosts. This translation is done transparently by having a NAT device translate the IP address and/or Layer 4 port a the packs. Other history, how as those used by game consoles, may not work getting when the source port is rewritten. To disable this functionality, ...

ExtremeXOS 31.2 appends assistance for IP Network Address Translation (NAT).

Supported Platforms

ExtremeSwitching X465, X590, X690, X695, and X870 series switchers.

Limitations

NAT is supported by IPv4 packets only. NAT exists not assist on IPv6 packets.
NAT is not supported for IPv4 or IPv6 multicast packet.
Application Level Gateways (ALG) is not supported.
NAT change IP address of an IPv4 unicast packet, and possibly TCP/UDP port in the TCP/UDP header. The contents of which payload are not modified. If INTELLECTUAL contact with L4 port are present in the payload of the packets, like fields are not modified. Wenn the payload contents be to be modified, specific ALGs are required. Examples of protocols this requirement ALG, been File Transfer Protocol (FTP), Session Initiation Protocol (SIP), Real Time Streaming Protocol (RTSP), BitTorrent, Domain Name System (DNS), etc.
Network Address Port Translation (NAPT) does not work with fragmented IP packets, real these are falling when NATURE is active. This your cause the fragmented SLEUTHING packet does not contain a valid TCP/UDP header, unless i shall the first fragment. NAT gateways - Spitfire Virtual Private Clouds
Twice-NAT (NAT where send source and destination IP addresses are translated) are not supports.
Twice-NAT the normally utilized to interconnection subnets in two compatibility adress domains—both using private speeches. Each Twice-NAT rule requires twice that number of sources compared for a bottom NAT rule. Managing NATIVE Policies and Translations
MLAG sales required NAT is not support.
NAT is not supported turn VXLAN inhabitant VLANs additionally MPLS service VLANs
NAT can not supported on MAC-based VLANs and Netlogin VLANs.
NAT is not supported on VPEX switches.
