Configuring network interfaces
packet to. Before it forwards the packet back to the private host, it changes the destination IP
address of the packet from its public IP address to the IP address of the private host.
IP address and Port
This mode behaves like NAT, but in addition to changing the source IP of the packet from the
private host, it can also change the source port number. This is required if more than one
private host attempts to connect using the same local port number to the same Internet host
on the same remote port number. If such a scenario were to occur with NAT, the router would
be unable to determine which private host to route the returning packets to, and the
connection would fail.
Enable IPsec on this interface
Enables or disables IPSec security features for this Ethernet interface.
Use interface x,y for the source IP address of IPsec packets
By default, the source IP address for an IPsec Eroute is the IP address of the interface on
which IPSec was enabled. By setting this parameter to either PPP or Ethernet and the
relevant interface number, the source address IPSec uses matches that of the Ethernet or PPP
interface specified.
Enable the firewall on this interface
Turns Firewall script processing On or Off for this interface.
Enable DNS inbound blocking
Enables or disables blocking DNS requests on the Ethernet interface, to prevent the interface
from responding to DNS requests over this interface.
Enable DMNR advertisement from this subnet
Enables or disables the subnet defined on the Ethernet interface to be advertised on any
defined Dynamic Mobile Network Routing (DMNR) tunnel. DMNR is available on Verizon Wireless
Private Networks. DMNR provides direct access to devices on the Local Area Network (LAN) at
your company's sites by dynamically advertising locally IP subnets attached to the router's
Ethernet interface(s). Contact Verizon Wireless for more details on DMNR and whether your
network uses DMNR or is eligible for DMNR. For more information on configuring DMNR, see
the Digi document Application Note 53: Configure a Digi TransPort Router to use DMNR
(Dynamic Mobile Network Routing), available on www.digi.com.
Remote management access
The Remote access options parameter can be set to No restrictions, Disable management,
Disable return RST, or Disable management an return RST.
