4. SUA Notes

Tested SUA/NAT Applications (e.g., Cu-SeeMe, ICQ, NetMeeting)

Introduction

Generally, SUA makes your LAN appear as a single machine to the outside world.

LAN users are invisible to outside users. However, some applications such as Cu-

SeeMe, and ICQ will need to connect to the local user behind the P-660. In such case,

a SUA server must be entered in menu 15.2.1 to forward the incoming packets to the

true destination behind SUA. Generally, we do not need extra settings of menu 15.2.1

for an outgoing connection. But for some applications we need to configure the menu

15.2.1 to make the outgoing connection work. After the required menu 15.2.1 settings

are completed the internal server or client applications can be accessed by using the P-

660's WAN IP address.
