This feature allows a switch to statically modify the source or destination IP (and optionally the L4 port) for a transit packet. Static NAT support on 7050X3, 720XP and 720D platforms was first introduced in 4.21.6F. Starting at EOS 4.35.0F, NAT functionality is supported on certain 7050X4 and 7358X4 platforms.

The packet path, prerequisites, and restrictions listed in this document apply to this feature as well Dynamic Twice NAT is a variant of the dynamic NAT feature where both the source and destination IP can be modified while forwarding a packet. One of the IP addresses will be dynamically assigned, while the other will be statically assigned.
