Can Prestige behave as a NAT router supporting IPSec passthrough and an IPSec 
gateway simultaneously? 
No, Prestige can't support them simultaneously. You need to choose either one. If Prestige is to support IPSec 
passthrough, you have to disable the VPN function on Prestige. To disable it, you can either deactivate each 
VPN rule or issue a CI command, "ipsec switch off" from SMT menu 24.8. You can get into SMT menu via 
either telnet or console connection. 
 
 
Wireless FAQ   
 
What is a Wireless LAN ? 
 
Wireless LANs provide all the functionality of wired LANs, without the need for physical connections 
(wires). Data is modulated onto a radio frequency carrier and transmitted through the ether. Typical 
bit-rates are 11Mbps and 54Mbps, although in practice data throughput is half of this. Wireless LANs can 
be formed simply by equipping PC's with wireless NICs.    If connectivity to a wired LAN is required an 
Access Point (AP) is used as a bridging device. AP's are typically located close to the centre of the 
wireless client population.   
 
What are the advantages of Wireless LANs ? 
 
a. Mobility: 
Wireless LAN systems can provide LAN users with access to real-time information anywhere in their 
organization. This mobility supports productivity and service opportunities not possible with wired 
networks.  
 
b. Installation Speed and Simplicity: 
Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through 
walls and ceilings.   
 
c. Installation Flexibility: 
Wireless technology allows the network to go where wire cannot go.   
 
d. Reduced Cost-of-Ownership: 
While the initial investment required for wireless LAN hardware can be higher than the cost of wired
