Cooper Bussmann 615M-1 Cellular Data Modem and IP Router Series Manual
Rev Version 1.0
If specific Port Forwarding rules exist in the IP Mapping Table, these rules take precedence over the DMZ host.
4.6 Friendly IP Address
Friendly IP addresses can be used with either port forwarding or DMZ to provide an additional layer of security.
When Friendly IP addresses are used, the 615M-1 will only forward packets to the LAN if the source IP address
of the received packet matches either the specific IP address or range of IP addresses specified in the Friendly IP
address field.
This feature can be disabled by entering 0.0.0.0 in the friendly IP address field. In this case, packets from
any host on the Internet can be forwarded to the LAN when either DMZ or Port Forwarding is enabled.
