Setting up DMZ host
The function of DMZ is similar to that of virtual server. The difference between vitual
server and DMZ is that DMZ opens all ports to WAN while virtual server opens ports
according to the demand of the enabled services. To configure DMZ host:
1. Click
Advanced Setup -> NAT -> DMZ Host
in the left side menu to open the
configuration page.
2. Enter the IP address of the host to be setup as DMZ host.
3. Press
Save/Apply
to activate the settings.
Allowing SIP request through NAT
NAT checks IP header only and translate the information into private IP address.
However, for applications that demand many dynamic ports for session control such as
Session Initiation Protocol (SIP), traditional NAT cannot translate the address because
lack of preset service ports. To enable such services while at the same time do not
sacrifice network security, DSL-N13 introduces Application Layer Gateway (ALG) to
allow SIP request going through fireware and NAT from WAN. To configure ALG:
1. Click
Advanced Setup -> NAT -> ALG
in the left side menu to open the
configuration page.
2. Select
SIP Enabled
checkbox to allow SIP request, or uncheck to disable.
3. Press
Save/Apply
to save and activate the settings.
Firewall - Outgoing IP filter
By default, all outbound IP traffic is allowed. You can block certain types of IP traffic by
setting up filter rules at DSL-N13.
1. Click
Advanced Setup -> Security -> IP Filtering -> Outgoing
in the left side
menu to open the configuration page. Click
Add
to create a new rule.
