NAT method

Only for Type of traffic = 3  *3" '-(

Select the NAT method for outgoing data traffic. The starting

point for choosing the NAT method is a NAT scenario in which

an "internal" source host has initiated an IP connection to an "ex-

ternal" destination host over the NAT interface, and in which an

internally valid source address and internally valid source port

are translated to an externally valid source address and an ex-

ternally valid source port.

Possible values:

• !3,," (UDP only): Any given external host may send IP

packets via the external address and the external port to the

initiating source address and the initial source port.

• #"" (UDP only): Like full-cone NAT; as ex-

ternal host, however, only the initial "external" destination host

is allowed.

• )#"" (UDP only): Like restricted-cone

NAT; however, exclusively data from the initial destination

port are allowed.

• #&" (default value) any protocol: Outbound, an ex-

ternally valid source address and an externally valid source

port are administratively set. Inbound, only response packets
