Possible values:

• $ B9 "" 84C (default value): The data

traffic that comes from outside.

NAT method

Only for Type of traffic = "$$ B 84C.

Select the NAT method for outgoing data traffic. The starting

point for choosing the NAT method is a NAT scenario where an

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

ternal" destination host over a NAT interface and where an in-

ternal valid source address and an internal valid source port are

mapped to an external valid source address and an external

valid source port.

Possible values:

• 22(only UDP): Any external host may send IP pack-

ets to the initializing source address and the initial source port

via external address and external port.

•  ""(only UDP): The same as full-cone NAT;

for the external host, howev- er, the initial "external" destina-

tion host must be used.

• !" ""(only UDP): The same as restric-

ted-cone NAT; but only data from the initial destination port

are allowed.

• -" (default value) any protocol: In outgoing direc-

tion, an external valid source address and an external valid

source port are administratively set. In incoming direc- tion,

only response packets within the es- tablished connection are

permitted.
