Easy Firewall Setup
Easy Firewall Setup
Although the SecureWall blocks all incoming traffic arriving at the WAN
interface except the traffic which is a response to a data request from the LAN or
DMZ networks you may wish to allow customized remote access to your
MultiCom Firewall or your local network.
The Easy Firewall Setup is part of the Easy Setup wizard of the Web Interface but
it can also be used separately on the MultiCom Firewall by using a web browser
to go to http://10.0.0.1/setup/fw/ (where 10.0.0.1 is the IP address of the LAN
interface of the Firewall.). Additional options are provided by the next 2
webpages.
Firewall Filters
The first part of the Firewall Easy Setup webpages allows you to enable or
disable the Stateful Packet Inspection Firewall to work along with the
SecureWall firewall. When filtering is enabled all traffic from the DMZ
network (if available) to the LAN is blocked. Additionally you can choose
to block NetBIOS traffic directed to the WAN interface or coming from
the LAN interface.
Additional rules can be customized using the Configurator software and is
described in the Lightning-Linux Reference Manual chapter on Filtering. When
you are finished click the “Next” button.
Host Mapping
If you make servers on your local network available to users on the
Internet (for instance a web or email server) you may enter the IP address
on your local network of those servers. Rules will be made to allow access
to these servers in the SecureWall and Stateful Filtering Firewall. External
users will use the IP address of the WAN interface and be redirected to
these internal servers.
