LAN WAN Inbound Rule: Allowing Videoconference from Restricted Addresses
If you want to allow incoming videoconferencing to be initiated from a restricted range of outside
IP addresses, such as from a branch office, you can create an inbound rule (see
IP addresses, such as from a branch office, you can create an inbound rule (see
). In the example, CU-SeeMe connections are allowed only from a specified range of
external IP addresses.
LAN WAN or DMZ WAN Inbound Rule: Setting Up One-to-One NAT Mapping
In this example, we will configure multi-NAT to support multiple public IP addresses on one WAN
interface. By creating an inbound rule, we will configure the UTM to host an additional public IP
address and associate this address with a Web server on the LAN.
interface. By creating an inbound rule, we will configure the UTM to host an additional public IP
address and associate this address with a Web server on the LAN.
The following addressing scheme is used to illustrate this procedure:
•
Netgear UTM:
–
WAN1 IP address (UTM25) or WAN IP address (UTM10): 10.1.0.118
–
LAN IP address subnet: 192.168.1.1; subnet 255.255.255.0
–
DMZ IP address subnet: 192.168.10.1; subnet 255.255.255.0
