Select what kind of NAT this rule is to perform.
Virtual Server - This makes computers on a private network behind the ZyWALL/USG
available to a public network outside the ZyWALL/USG (like the Internet).
1:1 NAT - If the private network server will initiate sessions to the outside clients,
select this to have the ZyWALL/USG translate the source IP address of the server's
outgoing traffic to the same public IP address that the outside clients use to access the
server.
Many 1:1 NAT - If you have a range of private network servers that will initiate
sessions to the outside clients and a range of public IP addresses, select this to have
the ZyWALL/USG translate the source IP address of each server's outgoing traffic to
the same one of the public IP addresses that the outside clients use to access the
server. The private and public ranges must have the same number of IP addresses.
One many 1:1 NAT rule works like multiple 1:1 NAT rules, but it eases configuration
effort since you only create one rule.
