The following table summarizes the NAT mapping types.
" Port numbers do not change for One-to-One and Many-One-to-One NAT
mapping types.
SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ProxiOS implementation of a subset of NAT that supports
two types of mapping, Many-to-One and Server. The LAN-Cell also supports Full Feature
NAT to map multiple global IP addresses to multiple private LAN IP addresses of clients or
servers using mapping types. Select either SUA or Full Feature in NAT Overview.
Selecting SUA means (latent) multiple WAN-to-LAN and WAN-to-DMZ address translation.
That means that computers on your DMZ with public IP addresses will still have to undergo
NAT mapping if you’re using SUA NAT mapping. If this is not your intention, then select
Full Feature NAT and don’t configure NAT mapping rules to those computers with public
IP addresses on the DMZ.

" You must create a firewall rule in addition to setting up SUA/NAT, to allow
traffic from the WAN/CELL to be forwarded through the LAN-Cell.
