Internet Access for the LAN using DHCP and NAT
DHCP can be used in combination with NAT (Network Address Transla-
tion) to provide easy Internet access for a complete LAN. The main ad-
vantage is that PCs on the LAN don’t need to be configured individually.
A simplified configuration using this setup would involve:
1. Configuring Network Address Translation on the V!CAS
(only one official IP Address is required).
2. Configure V!CAS as DHCP Server.
