If your ISP didn’t give you a Service name, leave that edit box empty.
2. Check the NAPT check box. This switches Network Address Port
Translation on. NAPT is also known as Internet Connection Sharing.
3. The Share Ethernet option can be used for sharing the single ethernet port
for both WAN and LAN, in a situation like this:
Figure 4-6 Using the Share Ethernet option
When the Share Ethernet option is OFF, only traffic that has a destination
outside your subnet (i.e. traffic destined for the internet) will be forwarded
from the wireless LAN to the Ethernet port. Use this setting if the Ethernet
port is only connected to your internet connection (e.g. ADSL modem).
When the Share Ethernet option is ON, all traffic from the wireless LAN
will be forwarded to the Ethernet port and vice versa.
This is useful if the Ethernet port is connected via a hub to both your
internet connection and to clients on your LAN.
If you use this option, both LAN and WAN traffic will pass through the
Ethernet port. In order to prevent your LAN traffic from ‘leaking’ onto the
internet, you must use PPPoE for the WAN connection (this depends on
your ISP).
If you ISP doesn’t offer PPPoE, you can only use the Share Ethernet option
if you use static IP addressing on your LAN. In this configuration, your
LAN traffic will ‘leak’ onto the internet.
If you want to use DHCP and the WAN connection doesn’t use PPPoE, you
