For Enable Intelligent NAT, leave the default setting, which is

Yes,

in order for the

LAN Modem to better support Internet applications and games.

The ISDN LAN Modem delivers all unsolicited TCP/UDP packets to the workstation
that is currently communicating with the remote host that has generated these
packets. If you set this field to

No

, all unsolicited TCP/UDP packets are delivered to

the default workstation.

16

In the Default Workstation for Incoming Packets field, specify the workstation to
which all unsolicited TCP/UDP packets should be delivered.

Note that if the Enable Intelligent NAT field is set to

Yes

, the ISDN LAN Modem

first attempts to deliver the unsolicited TCP/UDP packets to the workstation that is
currently communicating with the remote host that has generated these packets.
Only if no such workstation is found are the packets delivered to the specified
default workstation.
