5.2  WAN/DMZ Configuration
This  section  describes  how  to  configure  WAN/DMZ  settings  for  the 
WAN  interface  on  the  RX3042H  that  communicates  with  your  ISP. 
Youʼll learn to configure IP address, DHCP and DNS server for your 
WAN in this section.
DMZ (short for demilitarized zone) is a host or a small network that 
sits between a trusted internal network, such as a corporate private 
LAN,  and  an  untrusted  external  network,  such  as  the  Internet. 
Typically,  the  DMZ  contains  devices  accessible  to  the  Internet 
traffic,  such  as  Web  servers,  FTP  servers,  SMTP  (e-mail)  servers 
and  DNS  servers.  The  DMZ  contains  no  corporate  confidential 
information.  In  the  event  that  the  DMZ  is  compromised,  no  other 
company information will be exposed.
Note: Only static IP connection mode is supported for DMZ.
5.2.1  WAN Connection Mode
Five  modes  of  WAN  connection  are  supported  by  the  RX3042H  – 
static  IP,  dynamic  IP,  PPPoE  (multi-session),  PPPoE  unnumbered, 
and  PPTP.  You  may  select  one  of  the  WAN  connection  modes 
required  by  your  ISP  from  the  Connection  Mode  drop-down  list  in 
Network Setup Configuration page as shown in Figure 5.2.

MTU
You may specify the maximum size of the transmitted 
packet. For PPPoE, the range of MTU is from 546 to 
1492. The default value is 1492.
Disconnect

(min.)
Enter the inactivity timeout period at which you want 
to disconnect the Internet connection when there 
is no traffic. A value of 0 means no activity time 
out. Note that SNTP service may interfere with this

SettingDescription
LinkSelect a port to configure. Available options are

Connection 
ModeSelect PPPoE Unnumbered from the connection 
mode drop-down list.  Traditionally, each network 
interface must have a unique IP address. However, 
an unnumbered interface does not have to have a 
unique IP address. This means that when this option 
is selected, the WAN and the LAN use the same IP 
address. Network resources are therefore conserved 
because fewer network IP addresses are used and 
routing table is smaller.
